Not bad at all
much better than your old chops
imo chop needs some orange hue like this
and also there is 1 small thing that u forgot

also chop is low res
and in future dont forget to work a bit on details cause they are the half of the chop

There's a lot of good in this chop!
Background fitted and changed well, rims fitted well, everything working together and making sense

As gile said, the overall resolution of the chop is not so high, but it's just about suitable I think - make sure you use High Resolution bases in future
The biggest mistake I can see, is the reflection of the yellow lines on the side of the car - you've just pasted it over other reflections. If you look at the light 'bar' lower down the door that these yellow lines colour, the reflections of the ground shouldn't be here. It's light like that because it's pointing upwards and reflecting the sky, so shouldn't have anything from the ground visible

Other than that, it's actually a very good chop - well done!
