Nice looking chop this, there are some issues, but we'll get to them later.
I'd like to start with the general design of the car. All the basics of a good chop are there. Bodykit, rims and it's lowered. The kit looks okey I think, it's not super pretty and it's not ugly. The sideskirt is simple, but still adds to the cars general appearence. The backbumper is a bit more interesting. It's cool, but I am not to sure that it fits the car. The lines on it are all very round an flowing, but if you look at the car, most of the lines are very straight. I like riced out cars, such as this, but I also like when the bumpers fit the general design of the car, and here it's borderline if it's to far in between! Love the twin exhaust though!

Beafy and cool, and give the car a lot of attitute. Also really nice work with shaving the trunk, but i'd wished to have seen the same with the trim on the side and door, to make the car as smoth all around.
If we move over to quality there are some issues. If we start with the back bumper it's off in color. It works quite well on the trunk I guess, but if you look to the left of the taillight where the bumper meets the rest of the car, you can see that the car has a dark cyan color, and the bumper is very bright. These two colors should be the same! Cause the light is failling in the same way on both. The easiest solution would be to select this area with the pentool or other with high feather, make the selection from where the bumper meets the wheel to the line going straight down from the taillight, and make that area darker using CTRL + U. That should do it for a quick fix I think

Another issue is the contrast of some pieces, like the exhaust, they are a bit bright. If you look at the "dark areas" they are sort of a dark grey, but if you look in between the spokes on the tyre you see that the "dark areas" are completly black! These should be the same. Doesn't matter if you get it wrong always, just that they are equal everywhere. This makes the chop consistent, and you can get away with some errors

hehe. Our little secret ey
Overall a good chop. Keep at it, and don't worry about all the details I mentioned above, these are things that come with time. Study other chops and pictures, and you will soon get a hang of it!
Cheers!
