I think you really needed some blue to do well in this challenge, all of the high ranking shots had all three primary colors.
I think the main distraction is the lighting, looks like on camera flash, a bit too bright and harsh on the front bumper. Maybe a tripod with a longer exposure would have created better results.
Like the angle but there are a lot of distracting elements in the background that could be improved with a different one. I am sure you couldn't have moved the car so perhaps you did the best you could under the circumstances.
Overall pretty good shot, I bet the owner would like a copy :)
I think you might have scored a lot better if you had just taken a picture of the brilliant red spoked wheel (and yes I konw that you would then have lost out on the yellow and blue lights) however I do not feel as though they really add anything to this shot, and the the other cars in the picture are rather distracting. If you wanted to keep the lights, prehaps a tighter shot on the front wheel with just the left set of lights and the grill might have been a lot more interesting.
The color feels incidental, not central, to this shot, so I have to grade down a bit to leave room at the top for people who made the theme the star. Also, it's incredibly dark and muddy-looking, except for one part of the bumper.
