If there's one thing I can comment, it's probably the outlines. Perhaps it would help to use lighter outlines (esepcially the purple body) to soften the appearance of the vehicle?
Hi :)
It's my creation, original 100% (it's based on a classmate's car).
Looks good, but please specify if you used a reference, and link to it if you did.
That's the real color of the car :), but thanks
