You have alot of good ideas, just need to work on the execution and polishing the final image.
-The wheels are a bit too over saturated
-The bolt on arches' shade of white dont match the car body, so tweek around with hue/saturation or rebrush the panel sourcing colour from surrounding areas
-Window is very blue reflecting the sky, but the snow/ background is pure white.
Just make sure the car sits in correctly and fits the surrounding environment!
Ideas are nice, keep at it!
