Great stuff!
The attention to detail is awesome, the idea is interesting, and overall it's a well balanced piece. However, I don't feel the movement of the competition, like they're all standing still in different positions. Sure the smoke trail of the mayor robot gives a hint, but I wouldn't think it's enough. Nonetheless, I can't draw anything 1/10th as good, and I really enjoy this drawing style so.... good job and keep it up! 9.
