your range of colours and their use in textures makes me very happy. its awsome work to be sure, very skillful, and to be honest, i envy you that, even if its clever use of overlays.
but your knowledge of anatomy, both on the texture side, and the model side seems to be lacking, id really try to study that as much as you can.
the only other thing ive noticed in your consistancies, is that your textures are always too detailed for your meshes. it comes off as crowded, and not too well thought out. for example. hes got all that moss and grass growing on his shoulders. i would have thought a couple of/more alpha planes sticking up, and hanging down would look better because it looks so flat right now.
