Shadows are well placed. The bomb even have a reflection of the head. Have slight influence from Megaman/Rockman, I believe.
If you make it even more mecha-like, then it's much cooler (in my opinion, though). Adding more connection lines (I mean, machines are connected from smaller metal pieces). But it's good as it is now!
