neat character overall. The texture is incredibly noisy, though. I'd be interested to see the actual texture as it looks like MOST of your shading is done by your lighting setup. You do not appear to have painting in much into the diffuse map.
Hmm, he's good. Few comments though... I find his overall design to be quite unoriginal and boring. When I first saw this guy I immediately thought of Gorge from UT2K3 with a splash of Warhammer 40k marine. I see a lot of sharpened detailing in the grittiness of the material used to create his armour, but no depth…
