Davidson, thats awesome dude, is that captured from unreal ed? the slight stylization looks pretty neat. would you mind showing your material setup if it is unreal, looks like you have some cool fresnel action going on somewhere in there for the spec.
I really love your model thomasp ! Here is an in-game screen of the 3D model of the concept here. In-game render made on the Unreal Engine 3 with Unreal Tournament 3 (The background is an UT3 map: Islander). Polycount: ~3600 Tri. Textures: 2048²*(Diffuse+Specular+Emissive)
