Here's my opinion
1st: Every texture except for the back of the legs + thighs is too cluttered, not to come out offensive but that's just the way I see it.
2nd: I suppose you have seen this before but the feet + torso textures are too stretched out correct planning/mapping could hopefully fix the problem.
3rd: I don't get what you are trying to portray with the head in comparison to the rest of the set. The head differs in effects/techniques and seems awkward when viewing the set in general.
All in all 6/10
