New side makes it look like a BMW 3-serien. You should replicate the small shape starting from the front arch all the way to the bottom of the rear window and also simplify the corner on the car's shoulder line. It's too sharp and it's the one mainly making it look like a BMW.
Paint effect looks really good! Just remember to add the similar yellow lighting on the wheels onto the car's paint.
EDIT: Here's a picture to help you.
