Looks very nice, I think it reminds me of some transformer or something else.

Only the feet seem to be a bit short and clunky and the elbows are too big for my taste. Did you know that the foot of a human is as long as the lower arm? And Svenskmand is right, all faces should be smooth shaded (click on Set Smooth) and edges that should be sharp must be marked with Ctrl-E -> Mark Sharp. Then you can add an Edge Split modifier and the edges will be sharp. And the hand/claw needs some more work.
