This is amasing and making me drooling, cause I'll never draw like this, but can I say a little IMHO? I've saw this horse have three head just when looked more carefully. I think, it's because the line, wich aparts first and second head is too light. Once again, it's just IMHO.
Oh, that's gorgeous! My favorite parts are the delicate little highlights picked out in the wings. You make that look so effortless, hon! The tail looks like... one of those firecrackers that shoot sparks. I can't wait to see what else comes up!
