Ah, gotcha.
Anyway, if you recal, mine's not suposed to have 3D effects and shading. Like I said, it was dificult to understand enough without shading, and as for the 3D I will say this once again, mine is supposed to be a blueprint. A perfect side view. No angle. Mine is symetrical down the middle, you just can't see it because it's a side view.
Anyway as I said, I'll get to work on the Polaris Mk II. I'll try to work out some of the problems you stated, such as making it a bit less busy and adding some additional fire power. I'll also add some different shades of black and gray, but over all it's supposed to be a darkish-gray color, like graphite from a pencil.
EDIT:
I don't know how much of an opinion you might want from me after our previous "battles" but if you do here it is;
It does look great, but you might want to beef it up a bit. (By the way, I'm assuming it was meant for battle)
It seems a bit vulnerable around the arms and waist, places where the robot is pretty thin, and it wouldn't take much to shoot its arm off. Other than that and a noticable lack of weapondry, it seems fit for duty (once again, I'm assuming it's a battle robot)
