Exept the wheels ,exhaust and background, it's all made by me.

The mods on the car all look perfect!!
But the underground > tires + shadow look so much worse. (Black patches, lack of shadow, smudged underground, tire thread real low res and not matching etc.). Fix those and I'd say it MIGHT be towards pro.
I also think the dish on the front rim is way too wide, especially compared to the rear. (i know the donor, and you used a rear for the front and vice versa )

Keep up the good work though.

You're wrong with the donor, but my front wheel is bad fitted.

Aw damn

I don't like it... background is worse.
Correct wheel, change the background and it will be nice
