Poor robot.
Maybe he's sad because his lower half is nonexistant. I think he would benefit from some LED eyes, or maybe some kind of texture to the "screen" area, because as he is, it looks like he has a black hole in his head. Some shinyness? Also, his neck looks too perfectly straight. The base of the neck is completely immobile, not to mention the fact that his collarbone has no...I dunno, it just doesn't connect, get it? It might look cool if you segmented it (the neck, that is.) and animated appropriately. Everything else = right on.
