His face is what mostly bugs me, his eyes doesn't look right and he has a weird face.. Plus your diffuse textures and specular doesn't help to show the normal map underneath them.
Cap Hotkill, are you talking about third botton image? It is "Flat Diffuse"... :) Your character looks great, but there are a few things that I would change: -Increase the polycount on his belt, this part looks like has lower polycount than the rest of the character -you could include the total polycount and textures sizes…
