Wow, it's almost flawless, so far. You should add more details on the robot eye lighting, and make that thing just above the eyes less round, to give a more futuristic look, you know. The way it is now just doesn't match with the rest of the head. :/ Also, if you could add some more details at the top, it would be perfect. 9/10
edit: How the fuck did i get ninja'd after a whole day without anybody posting
