Nice chop buddy, I'm liking the white camaro, not something you see everyday.
But theres a few simple errors.
-The shape of the shadow is wrong, it should be sharper and more to the right due to the strong sunlight
-also the wheels are too blue, and does not fit the background, where it is a very warm/ orangey colour

The white paint of the car should be a bit warmer to fit in the background, so just try to run a photo filter (Image > adjustment > photo filter) on the car so it matches the background.
Nice looking chop all up, keep it up mate
