It's kind of poorly mapped. It also looks like you used the same texture for one side for the other (r_leg used for ll_leg, etc). The actual art though is great. I would say the head doesn't have colleration to the body textures. Its colours are different to the other textures. The torso is all the same textures.
Overall, great work but learn how to map. The mapping could make the difference. Also, try to not use the same texture for more then two pieces of the set. It's okay of it's symetrical though.
This could sell for about 7-10k
