Third times a charm....

So...any thoughts

- The shadow is wrong, it should be longer on the left side since the light comes from the right.
- The wheels are too bright and too big.
- The roll bar is wrong, it should go down inside the cabin not on top of the rear quarter panel, you cant close the roof or the windows with that roll bar.
- The car highlights are all gray, you need to put some background colors and reflections there.
- The intercooler could be a bit brighter to see it better.

Is a nice work but you need to work on the fundamentals more, things like reflections and how stuff work, i usually look at references before i do anything just to see how it works, here is a roll bar reference on a S2000 you can see that the roll bar goes inside the cabin and straight down to the floor of the car.

THanks icedestar for the advice

The black paint is too desaturated and the wheels need to be in a better quality.
Also for the next chop I'd recommend to work on a picture that is atleast 1600x1200 px, its much easier then for you
