but I would like to focus on this piece. It is good, but I think you haven't considered in the right way the effect of the fire's light on the face. I think the higlights should have been on the other side of the face... ^_^ Anyway good work! I like it! By the way, this is a good tutorial, if you haven't cheked it already.
I hope this comment will be useful... ^_^ If you desire, you can critique my works, too!
