This piece looks awesome overall but I would like to talk a little about the anatomy in this photo.. I don't know if it was done on purpose but I would try and extend the forehead a little bit upward and the shadowing around the eyes a little less dark and wide. The reason for the eyes is because compared to the shadowing from the rest of the body the eyes wouldn't be so dark unless it was really caved in. I would suggest to do a little bit of photoshop work to just lighten the eyes and make the hair colors darker to make it less blend in to the skin color!
