This is really, really great stuff. The horse's anatomy is a bit off, but other than that it's fantastic. Have you done any pro work in illustration? I could easily see this being a fantasy RPG illustration or the like.
This is beautiful, i have a slight obsession with things that glow however ^^ but this is fantastic, i think a tiny bit more work on the horse and it would be perfect. haha but i suppose i cant talk my work isnt a 10th as good as yours.
