you're getting better and better, but this is still too blurry, i hope you know what i mean by blurry, its the worst ennemy of the resolution quality.
Apart from the major bluriness, i find that his metal could use some blue tints as darker shading to increase the feeling of metal, and give it a cold feeling. well it's another of these skin featuring stripe-like skinning. it had potential, but too bad you made it so blurry and somewhat had a low color palette.
