Nice try on this one! The added refs on it look pretty realistic. But the darkened rear window needs some more reflections. It looks fake atm. The front doesn't look very realistic, but I kina like it
The wheels are a bit too small and the rear one is off. The bg looks off too.
But overall pretty well done, great job on the reflections

update

The updated car with a new background (not the one you used before) would be great,
I like the front and the rims also look awesome!
