Marcus Fenix from Gears of War. He's not wearing the chestplate, though. I took some liberties, basically I just wanted to get through the main points of his character, with the size, the bandana, the scars, etc.
I was going for a dark piece with a single, dim light on the ceiling. I think he looks pretty cool. I was going for a stylized look, that's why the hands are so big.
