Its not doin' it for me. Hope the negative feedback is OK, just my opinion. Check out this page: http://eddiehollon.com/ They do paint renderings for race cars and have some really hot schemes. I am sure they would do an amazing job, but it's probably cost prohibitive. At least you could get some ideas if you are interested. I know them from Myspace, http://www.myspace.com/eddiehollon
I like the color scheme. Good choices there. I think the rear upswept scallops are fighting the front panels and the body lines. Try getting rid of them and raise and curve the front black scallop so that is follows the curve of the fender line a bit closer, and I think that might look nice. Is the car is going to be lettered and have decals? If so, I would work them out in advance too. Might make you want to tweak things a bit more.
I feel that graphics on a race car should give you the feeling of forward motion even while standing still. I am not feeling that with your original design. Seems there is to much of the accent color in front and less in the back. What are your thoughts for the hood,roof and trunk? Sorry just my thoughts.
I like it, but ONLY if you have the beefy tires and the flat rear spoiler. Those graphics look FAST, and wouldn't look good on a car that is not fast. All the pics shown on that other site with the 12 pic examples...looks like a fast car. But if I put that paint on my car, which is faster than 98% of the cars on the street, but slow compared to any drag car, it would just look ridiculous. So, if it is a drag car, with HUGE slicks, tubbed, roll bars, wheelie bars, and a chute, then that paint would look GREAT Just my opinion, though. And it usually sucks...
