Interesting build, though the colour scheme is a bit…surreal. It can be a bad thing, or a good thing depending how you decide to think of it. Nonetheless I like what your going for, but a bit too gappy and colourful for my taste. I’d like to see more mocs from you since I bet you have more than 2 mocs.
I’ll agree with Altron here, the colors need a little more control. However, the build is pretty good in my eyes. Maybe you could try covering up those axles on the back with some armor.
