So yeah, another chop, I can honestly say at the end i didn't do my best because, My dumb self chose a low quality base. (Genius right ? ) But yeah just wanted to share my idea with you. SO yeah i can say some mistakes by myself, 1- the side of the car too much saturated, 2- some little details(Little parts) are colored incorrectly. And yeah, So basically this was to share the Idea of what i thought about. (Well it was actually a good practice, I keep learning my brushing skills and even this bad chop/failure helps to improve)

Ok, red on car is too strong. U should change red saturation. Also u must fix selections. Try to use PEN tool for selections. Look at YouTube for tutorial. Good luck with next chop.

OK I'll try to improve

the front bumper is original i give you one vote to motivation

it's to vivid for me,and looks like the car is little bit got squished. hold shift when you transforming the size of the car, that's all. hope you get better and better...
