The one in my signature and avatar. A rainbow on clouds, simple, pretty, and classically MLP. And if you think about it, it's really the G1 MLP logo without the text.
A blue rose, of course. Because I love blue and roses are delicate and beautiful and smell great but have thorns (I kind of feel roses represent all women).
If I had a second choice it'd be a blue (or burgundy) dragonfly to represent the autoimmune disease I battle. It's represented by the dragonfly and a burgundy ribbon.
A camera (vintage Polaroid for good looks + awesome factor) and a pile of polymer clay blocks. On that note I should make a new pony OC. One that sculpts!
my ponysona's name is lazy bones and her cutie mark is cross bones with little sleepy zs i think i relate to that a lot but i'm not sure if it would be my actual cutie mark because i don't know if i'm good at it exactly. i don't really know what i'm passionate about. maybe toy collecting or writing letters? an envelope cutie mark would be cute.
