That's right, over a thousand ponies in a single image! That number blew me away! And while such a high number did prove to be challenging (and I cannot apologize enough for how long this took to finish), I want to give a sincere thank you to every person who participated, submitted their OC, drew OCs for other people, and helped spread the word! Thank you so much <3
If you are crazy and want the full resolution of this image (18000 x 12000, 100MB), you can find it at https://derpicdn.net/collab19.png — I do not recommend trying to download this on mobile or slow internet connections.
Thank you everyone who participated, and I hope to see you all back next year for the 2020 Community Collab!
