The wheels and window are very blue, but the background is a warm/ sunny orangey colour. So you need to reduce the blue areas so the parts blend with the image.
its not a bad attempt overall looks apealing, but needs some fixes, like hui said the windows. the ground near the car is very bright when the sun is behind that ground area should be darker, also all the bodykline should be mpre prominent, and the reflections less blurry and th rear wheel is off
