hey
Well my first thoughts were that I think you should have the legs/teeth as a different color, maybe silver?
Anyhows that's it for now, might add some more crits or whatever later.
edit
I actually done a couple of edits a little earlier, but I think I will wait until you have made further progress? unless you want me to post now?
Anyhows, I think the light source isn't strong/defined enough, and the laser looks too solid. Hmm, I don't think there is much expression or something, and nothing much to show it's a robot... well it doesn't look functional.
Ohh, and keep at it 
.

The teeth/legs would look a bit better with a different color thanks for the tip I'm going to work on it a bit more at some point today and I'd love to see your edit when you're done.
