That's an amazing Cerbera you got there! That blue is so bright, like a streak of lightning. I know the whole electric blue thing is a little cliche, but that's about all I can compare it to. I think the upper and lower black sections look fine the way they are, but you could paint in a couple more streaks of some color; blue, maybe, or white? I don't know how you would smear it across the pic in a straight line because it's pretty hard to draw it that straight. It would emphasize the speed, though.
I can't believe nobody corrected me when I kept calling that B-dub an "M Roadster". What an Idiot, I can't believe I screwed that up with my somewhat rampant "names and numbers" magazine knowledge. I know it's a Coupe, as opposed to the roadster, I just had a blonde moment. I was wondering as I was typing why it took so long to punch in the car's name.
