Innovation is not about designing a new shape....Is about introducing new features.....You just didnt explain them.....I cant see anything new this car brings....Which is a contest requirement.

Regarding the aerodynamics of your car, so that you know, where the rear spoiler is located, it wont do anything at all. Zero ! You wont have flow reattachment on that area, hence the spoiler wont have a great effect.

And learn how to take a criticism.....I asked for the innovation, just to help you, or make you think, you probably need to incorporate something that is new!

Good luck!
