I totally disagree with the eyes, the glowing ones you've got now look cheap, much prefered it with the hollow calm ones. You could've made him equally menacing with animation.
I agree with the crit on the skin, I don't neccessarily think that the texure you've got is bad, it just lacks detail, like abs, bellybutton and nipples! Maybe shoulderblades at the back, clavicle and collarbones. I think if you just hint at these with the shading/normal map, your texture will look much more convincing.
With regards to the model itself, and the way that you've improved in the way that you model characters, this one is by far the most anatomically convincing of any of the characters you've created so far. Very nice.
May I make one enquiry though? I looks from the stretching on the tops of the arms and the sides of the face like you are planar mapping the UVs along the Z axis. Why not pelt map the face and sleeves so that you wouldn't get the horrible stretches. They aren't too noticable right now, but as soon as you add norm/spec it's going to be glaringly obvious!
Great work though
I want robotic legs.
