im going to have to be honest, eventough the chops looks good, i think it needs a lot of work,
.the car rflections are way to "studio" looking for this background, you need more refs, expecially on the bonnet and front windshield (tree reflections),
.the shadow on the floor is to static, like a plain box, needs more dynamic and parts more faded, cause this way its making the car look like its floating,
. i find the front logo and the roof rack to saturated for this, if you wanted to try a sunset / sun bloom environment, it would never look that way,
. the roof rack is missing its own shadow and reflections on the car roof
. there is completely no shadow under the tires
. the rear car cutting could be a bit better
. and last but not least, dont get me wrong, but im completely not understanding the whole environment lightning, that big white dot on the top doesnt look to much like sun bloom, cause it comes from a part of the image where it should be actually shadow, cause the other part of the image is brighter, and the ground shadow is pointing to the oposite direction of your "light" source.
so i think there is not much done on the car other then some "trent" modifications, so im sorry the chop is good, but i cant see this as a very good chop
but keep it up, i think you could do a bit more to it
