I like it too. Your original idea of the roof scallops that complemented the front I think would have looked better, and I prefer the FasKolor purple myself, but it still looks like a good job as is.
Thats why when painting for a friend, I let them pick out the color and theme (flames, scallops, art concept, carbon fiber, etc) and thats all. I don't let them get too technical with it, because it ALWAYS turns out different, even from MY original idea.
