I drew this a looong time ago! Her name is Heaven Scent, she is a crystal horse, and she is Diddgery's Original Crystal Horse!
I actually loved drawing her. I was absolutely astounded at how other horse drawers (specifically Didge) could put the Crystal Horse overlay on their crystal horses; I couldn't figure out how they did it. They actually just found a texture and overlaid it on the horses, but I didn't realize that and so I tried to paint her crystalness. I think I did a good job, especially in her hair!
