Excellent scene! If there's something harder to make than clean/futuristic textures, it's realistic-looking dirty textures. I think you made the windshield too dirty though... it's now the dirtiest part of the car, and the fact that the wipers are longer than the wiped areas springs into view. Other than that, pro work!
really great work , for sure , . but i would say that there is 2 things that i dont like about it , .. the trees in the background , i think they look too geometrically perfect and unrealistic , and the light on the front bumper ,it looks a bit blurry . other than that's it looks really great , the modeling , lighting . congrats
