Some suggestions, all personal opinion. Turn engine bay into a front boot or similar rather than an empty space where an engine should be Shorten wheelbase Fix the minor texture issues Fix rear window vent, I understand what you were going for, but it looks a little weird Make it look a little different from 200BX
I am working on a design change that makes it shorter but the wheelbase will not be changed due to it handling so well as it is. And the firewall window will be slightly downsized and exhaust enlarged but I like to see the engine so I will not cover that. + the side vent will be altered to look cleaner.
