It looks quite good mate!
There are some things that needs to be improved though!
If we start with the design ;
I like what you have Done Front bumper fits quite well to the original Lines of the car imo, However i dont like the side skirt as it has too much shapes in it

You've made a design that is very subtile yet stylish, so that is good.
The brushing looks good however it could use some improvements!
1 * - I believe that the shadow on the side vent is way too strong, Try to just take the eyedropper tool, Choose a darker color from the car, Then redoing the shadows, with the brush tool! as the colours need to flow together unless there is an edge on the car!

2 * - once again i believe that the shadows are too strong, on the sideskirt!
Try to use a good reference picture when you're a new brusher ! it will help you understand the lightning more

* really helps me and even Elite Artists! *
Theres also some quality issues such as the Front window wich is very low res, along with the wheels ! This is a very sad thing as they drag the chop down really much
Also to me both wheels seem to be off, but the one that needs to be fixed is the rear wheel
as it has waay to much Toe ;P
But a great chop! good work.
