I see your trying rounder shapes with your robot. The differences in the lift and right arms are a neat contrast. However, do you think this got a 3 out of 5 earlier because it looks slightly like it'd fall over backward? I had a similar balance problem with one of my mechs that looked like it would fall over forward. One thing I did to make the next one look better was something like putting that left leg further beneath the robot with perspective or make the left leg further spread out and away from the body. As it looks now, I'm thinking most of it's weight is on it's left leg.
That aside, it still looks awesome with the lights all over its body and arms.
