Thanks! She is my proudest creation, as far as pony OCs go. Her mane is literally one of the most fabulous things I have ever drawn. Her design gets compared to Rarity a lot but her personality is closer to Twilight.
 
Her appearance is meant to evoke classiness and a refined feeling. My goal for her design was to base her appearance on classy, expensive things in a manner similar to a lot of the aristocratic Canterlot mares, but more modern-contemporary, and based on what humans consider fancy, as opposed to what ponies consider fancy. Hence the reason for her sleeker, more minimalistic appearance, equine hourglass figure and brushed gold trim.

Lol. Well I think it’s an awesome ability :). On a side note, she is very cute. I like her

@ROMfullofpony  
That was actually an old ability of hers, and a joke one at that :P
 
She is a sparkly unicorn, of course she can poot rainbows. She’s just classy enough not to unless it’s a special occasion like the 4th of July.

@Da5ch  
So is it just her that can fart fireworks? Haha

@Da5ch  
Oh, so she’s like a golem then. Neat. I’m guessing her species are non-combative.

The Lightmares are a race of ancient, magically animated doll-like ponies who follow Princess Luna in her visiting ponies in their dreams to help ponies face their fears. A Lightmare can turn even the most horrible nightmare into a sweet dream.
 
Notably Lightmare cutie marks are abstract and have little bearing on their actual talent, if any bearing at all. Like Stargie’s here is just gold stars. It fits with her name but not much else.
 
And that armor/attire is actually part of her body. It is gold trim and fancy hard inlays with a rainbow sheen on them.

That’s some interesting armor/attire she has. I wonder what a lightmare does.
