It is spent minutes 20 there was a wish for just good picture
Base

Chop

Wow, very good work, especially for such a short period of time!

The Background looks nice and suits good, even the reflections you added are well done.
The wheels and the low suspension are very cool as well, looks good.
But the front intake you made looks a bit unreal and the lights are the same colour of the car, not like the wheels of the BG.
I´m not sure if the shadow at the left side of the pic is correct like that.

But yeah, even though some cristism this is a great chop for 20mins, keep it up!
