I would add at least some amount of blue on almost every surface facing the sky. That includes the whole roof line from the a-pillar to the c, on the car's shoulder and top of the wheel arches. I'd suggest making it a little over the top with the blue to get the lighting and hue variances look good and then just tone it down with opacity and blend mode.

Also, some white on the bottom parts to tie it better together with the bright ground.

Ok I'll give it a shot, thanks for the help

alrite ive worked on it and this is about the best i can do, its doing my head in so i think im finished haha

most likely without the gold ring around the wheels though, i accidentally turned the layer on
