Wheels are off in perspective. Just too wide too, compare it with the original. You have to keep the scale the same. You can move it around for wider placement but not that much that they simply aren't round wheels anymore
Colour isn't convincing, pro tip: never colour change a silver car. Maybe to white but otherwise don't.
The parts cut out in the windows to make the background more visible is too strong. You still have to add more window reflections over those parts.
Other than that it looks good
