I went through some of my old sketch fest art and found that I had done some corrections and clean up to this one. The old one is now obviously in my scraps. :)
I took the old MLP style basis (head/body balance) and added more realistic equine anatomy features. So now it's a chibi horse! heh.
To further remove it from "MLP" fan art, the "mark" is more like a brand or tattoo on her shoulder. Also, unlike MLP world, she is an earth pony in the clouds... >.>
Ok, so originally I forgot the wings, but I was drooling over drawing a Gypsy Vanner mare. ^.^
