the asymmetry of the eyes makes the little design in the centre look off centre. the eyes are sloping at two different angles, and that one has that chop downwards, in terms of natural design, that wouldnt normally happen, even if it is a robot straight out of battle, robots dont get lazy eyes.
might suggest that if you want the one eye to look battle worn and broken/deformed, then make it look obviously broken, sketch in the basic outline of the eye socket and then break bits away in a more logical manner
