He’s quite a mess, and I think part of that is the clashing textures. Some of him’s sleek, bright and smooth, other parts are heavily greebled and metallic. His feet are really big, especially near the back. I would also prefer if you used the ‘Nitroblast’ side of the head, as he looks a bit too much like Jetbug.
That said, his colour scheme is mostly consistent (Save the different shades of Yellow), and his backstory seems ok.
