A beautiful edit, indeed. Quite tasteful.

ooh, lovely!

@Imalou
 
Hello Imalou.  
I am the one responsible for this edit.  
You do not know what your kind message has meant to me. I have always been a tremendous fan of your work and it could not thrill me more to have your approval.  
I apologize that I did not seek out your permission first before posting this edit. I tried my best to make it abundantly clear that this edit of your original piece was not your handiwork, but the work of a stranger, but now I see that I should have done much better than that for your sake.
 
I also see now that it was shameful of me to try and remain anonymous for somewhat similar reasons (I didn’t want people to know that I edit the artwork of others for my own tastes and practice) when I did not pay you the same opportunity.  
I should have thought this through much more carefully than I did.  
If you wish it, I will gladly reveal myself publicly as the creator of this edit (and I may do so anyway just to insure the blame goes entirely to me).  
Inversely, despite your approval to allow this edit to remain, I am fully prepared and almost desperate to let you rescind that approval as people could still associate this edit with your artstyle and name.
 
This post is NOT worth your honorable reputation.  
Say the word and with every ounce of my ability, I will insure that this is gone.  
I am considering doing this anyway as I am now very embarrassed of my shortsightedness.

Hello!  
I’ve just noticed this on derpibooru, made me laugh a biti’m sorry, thoses giant balls are gorgeous haha !! I’m fine with edits, especially since this artwork is quite old, but I don’t really want to have my username/tag assiocated to NSFW and lewd artworks as I try to keep a safe image of my art for professional reasons. Just take off my name in the tags and I’m fine with it :)

@Princess Luna
 
Awesome!  
I could not be happier to hear that!
 
Sorry if I came across as too judgy or irate. I was just frustrated over how similar these tags were in comparison to the vast majority of the explicit material on the site.  
I’ll try to moderate myself a little better in the future in regard to my concerns.
 
You truly are best princess!

I’ve set this at Questionable. Not everyone agrees on that, but it’s a decent compromise and the anus technically hits Questionable due to having both inner shape and a bit of outlining.
 
I would like to further add in regards to “explaining to a kid” that, to my understanding, most children have seen dogs/cats before and would understand that quadrupedal mammals have things on their rears, unlike in the cartoons; they would probably not question it, but might question why most stuff ignores reality, as they wouldn’t know the reason for it.

AJ: Wow~…
 
Mac: A pony’s time as a farmer, rises and falls like the sun. One day AJ, the sun will set on my time here. And will rise with you, as the new owner of Sweet Apple Acres.
 
AJ: So this will all be mine?
 
Mac: Every apple here.
 
AJ: her mouth waters Every apple…

I recognize that I am in the minority in regard to the rating system.  
There’s really nothing for it other than to accept that fact on my part, but it doesn’t change how I feel.  
Pictures like this have no business being categorized as porn.  
We are simply going to have to agree to disagree on this point.  
Accept your win in the fact that most seem to agree with you on this.
 
And I appreciate you bringing this sites definition of anatomically correct to my attention. I was unaware that that was all that they wanted that tag to mean and it was the source of legitimate confusion on my part why the vulva tag kept getting auto added anytime I added that tag to a piece.
 
In regard to your art, please do not think I am in any way dogging on it. I am decidedly a fan.  
My confusion stemmed entirely from my misunderstanding of this site’s agreed upon meaning for the anatomically correct tag. I thought that the tag was merely a reference to any picture featuring anatomically correct genitalia and, clearly, I was not the only one under than assumption.  
I didn’t understand why you were seemingly ok with a mare possessing a penis being labeled anatomically correct, but the OP attempting to use the tag in reference to their attempt at drawing “realistic” horse balls was a problem.  
Now that I understand the tag to be referencing the vulva specifically it all makes sense to me.  
You don’t seem to typically add that tag to your art yourself anyway so that even further makes that old observation of mine obsolete. I apologize for my confusion and insinuation of hypocrisy. That was entirely on me.
 
Thank you for your advice as to how I can best find the art that I like. I already do most of that, but I appreciate the suggestion all the same. Most of my issues seem to arise from confusion over the site adopted meanings associated with many of the tags on here. I will try to pay closer attention to what derpibooru says that the tags mean rather than relying entirely on my own understanding of vocabulary. I forget to take into account the differing meanings words tend to adopt from place to place.
 
As for the anatomy discussion, I don’t know how we are to go about it other than a back and forth over what we view as accurate. I mean, I’ve had intact dogs my whole life and most don’t look anything like this in my experience. They typically tend to have a one-in-front-of-the-other sort of appearance aligned with the sheath. This, of course, varies from dog to dog and it doesn’t help how anatomically different the breeds can be from one another.  
If I’m being completely honest, I think that if I had to attach this genital design to anything, with absolutely zero context, it would probably be rodents.  
All things considered, however, I don’t really feel that there is a tremendous amount of physiological difference from mammal to mammal as far as the over all look of the testicles in concerned. There are a few really crazy looking ones out there of course, but the biggest difference usually tends to be size in relation to the rest of the body and how they are hanging from the torso more so than shape.  
The ones depicted here seems close enough to me to justify calling them a cartoony depiction of what a horse in this style would look like.  
Perhaps I have missed some detail, but other than them not hugging the torso quite tightly enough and hanging longways a bit too vertically rather than more horizontally, I don’t really see the problem. What detail about them are you zeroing in on that is making them look off to you?

@Woofy  

 
It has balls and anus. There is no possible argument against that.
 

 
If it is not human vag on pony, then it is most likely anatomically correct. The tag itself only regards with vulva.  
Also, I wasn’t so “adamant” when I was relatively new to art, you might have seen some of my old works.
 

 
I don’t mind, go ahead.
 

 
The simplest way to find good art is to follow the artists’ tags that you like. Find out who makes ponies the way you like and follow them. It would be better if you followed them on other socials like Twitter or FA as well.

@Mercurial64  
And as you can see, I have left the rating alone. I don’t own this website and it isn’t up to me how they wish to rate their art. However, I have every right to publicly disagree with that rating system when it labels some harmless piece of art explicit and banishes it away behind a porn wall.  
It should be questionable because THAT is what that word means. It is safe, but it contains some material that not everyone is ok with. Regardless, I have left it alone because I am apparently in the minority on this issue, though I wonder what the point of having a 4 intensity level rating system is if something as innocent as this isn’t allowed to dodge the porn label.  
This isn’t porn.
 
Upon reviewing the anatomically correct tag, it appears that you are correct insofar as this site is concerned. The blame, once again, seems to fall on an arbitrary decision to have the term apply only to female genitalia rather than be any sort of reference to the term’s actual meaning. I admit, I was quite curious why the vulva tag kept getting auto added any time I added that tag.  
I can’t argue with what the site administration have chosen for that tag to mean so I guess that I will once again concede defeat.
 
As to my comment on your library, I was referring to your posts, not your likes or favorites. You have actual posts with the anatomically correct tag in your portfolio and I failed to see how some of them meet the standard when you were so adamant that this one did not. This is neither here nor there though at this point because, by this site’s own definition, it was clearly in reference to the status of the vulva present in the picture rather than the actual anatomy depicted.
 
I still disagree that this is a depiction a dog testicles, but, at this point, it doesn’t seem to mater. The disagreement is moot. I’m still willing to talk that through privately, but I get the impression that it’s a conversation you aren’t really interested in having so I won’t pressure you over it.
 
I have meant no offence with any of this and merely wished to vent my frustration of the difficulty of finding some things on this site. That is, after all, what the tagging system is for though I admit that there was probably a better place to have done so.  
I apologize.
 
Have a good day.

@Woofy  
You can’t explain to kids, why this (anatomy-wise) show accurate pony has balls and anus. That’s why it must be tagged as explicit.
 
If you want me to prove why this isn’t anatomically correct and why it looks more like a dog, send me a private message, I will explain there.  
Also, I don’t pay attention to tags 100% of the time, if I liked a picture and missed a tag, it’s not that big of a deal.
 
But in this case, I noticed this picture not having explicit tag, then I checked other tags and saw it was anatomically correct for some reason. No, this is not anatomically correct.  
Not only this picture has nothing to do with anatomical correctness, it also completely doesn’t match with the tag’s description:  

 
You might have noticed when you added Anatomically Correct tag, it added Vulva tag automatically. Because that’s why that tag implies.
 
Leave the tags and quit fussing for no good reason, please.
 
Cheers.

The rating system on this sight is so weird.  
How the heck is THIS explicit in any way? This isn’t porn! Nor is it offensive. It’s casual nudity. I can point to hundreds of Renaissance paintings and sculptures way more graphic than this and that are completely acceptable to show children in school.
 
Why do we have FOUR ratings on this site (Safe, Suggestive, Questionable, and Explicit) and yet, two of them seem to mean practically the same dang thing on here while perfectly innocent pictures like this get shuffled off and lumped in with the mountains of porn never to be seen by anybody who doesn’t like seeing Fluttershy getting gang-banged by the diamond dogs?  
How is anyone supposed to find pictures like this when there is practically nothing setting them apart in the tags from every single porn picture on this site? I’m clearly no stranger to porn, but I actually like stuff like this and it’s like sifting for a needle in a hay stack to find the many many examples that didn’t happen to get caught by the Casual Nudity tag (which I see was, once again, forgotten in THIS picture’s tags). And I’m sure we can all see just how much use the Tasteful Nudity tag gets on here.
 
I’ll leave the rating alone since I guess that I’m technically wrong about this picture qualifying as questionable according to what the word apparently means to derpibooru’s rating system, but I get pretty irritated when there are 4 ratings on this site, but only Safe and Explicit seem to matter.
 
@Background Pony #3B4C
 
And don’t be such a doormat.  
I could find you hundreds of pictures of real life horses with balls that look identical to the ones you put in here. They aren’t photo realistic, but no one should be expecting them to be before allowing the Anatomically Correct tag. Ironically, I’d have a hard time finding a dog with similar testicles; those tend to line up long ways, one in front of the other along the dog’s body more so than most mammals and are significantly smaller. There ARE dogs with balls like this, but those are few and far between. These are perfectly passable for a horse and look perfectly appropriate for this art style.  
What’s more, I could find you plenty of pictures in Mercurial64’s library of a rainbow colored futa plowing a mare from behind (or something equally anatomically ridiculous) that Mercurial apparently has no problem with being labeled Anatomically Correct in the tags. I’m not going after Mercurial64 as I clearly enjoy his art, but I cannot fathom why you using that tag was even a blip on his radar. If THIS doesn’t qualify for that tag, then NOTHING on this site qualifies.  
I’m putting it back.

@Mercurial64
 
Thank you, Mercurial, for your kind reply.  
The show itself has debatable levels of anatomical correctness when compared to actual equines. I was merely attempting to match the art style to the best of my abilities.  
I have a lot to learn though and I appreciate your observations. I admit, I wasn’t actually using reference material when I was attempting this edit and was merely going for what looked right to me (filling my own mental checklist for artistic composition).  
Striving for correctness of anatomy is definitely what I was aiming for though so I will be sure to try and pay closer attention to actual reference material in the future. The fact that you had that reaction at all is telling in and of itself that I need to improve.
 
Again, thank you for your considerate reply. I hope to do better in the future as I learn more.

Thank you to all of you who have voiced your appreciation and support of this.
 
I was exceptionally nervous to upload this for others with similar tastes to enjoy.  
I didn’t want to step on anyone’s toes as I know that both nudity (tasteful and otherwise) and edits can be pretty touchy subjects in many art communities.
 
Also, thank you to Minus for linking to the original piece by Imalou. I didn’t realize that I could link to another page on this same site, but, in retrospect, that should have been obvious.  
I still maintain that it is entirely up to Imalou whether this piece remains up. I surrender any and all authority that I may or may not have over this edit over to the original artist. The last thing that I ever want to do is cause them any distress.

@Background Pony #3B4C  
Sorry, it was kinda harsh from me, but I can tell for sure it’s not anatomically correct. The original picture is not anatomically correct, to begin with. These ponies have a dog’s anatomy for some reason.

@Mercurial64
 
I suppose that I will default to your superior experience as a poster and artist on this site.  
I can’t help but feel that your standards for what does and does not qualify as anatomically correct are rather high though.  
I genuinely did my best and don’t feel that this is so very different from many other similarly tagged pieces on here.
 
I truly wish that you hadn’t removed that tag.

@Mercurial64
 
No, it isn’t.

how is this anatomically correct it’s dog balls  
also how in the fuck is this questionable

nice, good art, not like a shitty nsfw edits of episodes

@Raritybro
 
As another person who also likes to edit other artists work from time to time; no, but it can be a fun challenge, and sometimes you just find a piece of art that you desperately want to make a certain change to, just for the heck of it

did this really need to be lewded
