Basicly I think it looks great, but that comment won't help you improve it, so what follows is mostly critical. I think that the helmet, bow, and arrow head, could benifit from a texture map, they look a bit like they are made out of plastic to me. The tip on the arrow head looks rather blunt and rounded, it would seem more threatining if it looked sharper. The fletching is the same colour as the arrow shaft, which seems unusual. Perhaps the bottom right lip could raise a very little bit, the bottom lip looks rather more symetric than I think is should considdering the pronounced sneer on the top lip. I can't decide about the highlights in the eyes, they are on diffrent sides on diffrent eyes. It seems to me that from the point of view of physics they would both be on the same side, but I can't actually say it looks bad, it may even look better than more naturalistic highlights, you decide.
