This is a really ambitious piece. I can really tell you pushed yourself and it has paid off. The princess is stylized very well and you not only captured her at level 99, you captured a very well executed action shot in fantastic detail.
I knocked a star and a half for the wolf. The faces is good not great and the fur is detailed enough but flat. However, where it really falls short is in the proportions and posing. The rear legs appear short in comparison to the body and the forelegs are tucked unnaturally under the Princess. In fact, so much so that it makes her look like she is mounted on the side of the beast instead of on its back. That is a serious distraction for me as I ponder the piece.
I don't say this to slam the art or the artist, but I know how easy it can be to become so immersed in a piece that you lose track of parts of it. Good job overall and good luck in the contest!
