First up - great ideas

It's not often that someone is brave/creative enough to try and create a burnout scene, so well done for that!
You've also had a reasonable attempt at creating a new kit of your own design, something else which should be credited.
However I think the brushing lets it down a bit - I guess we all have to start somewhere, so do not be disheartened, keep trying, but perhaps work up from smaller parts like bumpers etc.
You should look more at reference pictures - real photos of real cars, then you can see how the colour flows and changes over the car - try not to let the colour become to strong, which I think is what has happened here. You should also try and add extra contrast between light and dark.
This is something I did really quickly, just to give you more of an idea of what I mean:
Mine is definitely not perfect - it would need much more detail and tidying to look correct, but the most important thing is the overall lighting.
Keep trying though

Good luck
