Very nice style. It reminds me a lot of the coloring and texturing style from the Shin Megami Tensei games on the SNES.
Great detail here. He's even got a 'junk-samurai-topknot' bolted onto his head, awesome.
Very nice, but I think the robot head should shade to the shoulder of the robot. And the robe he's wearing should have more shading, especially on the sleeve. The robot's chest with a strange lighting too, but my god, it was very cool.
