No sexy girl in your avatar, Zoxxy? You may lose credit for that.
As I said, I am not a big fan of the Enzo to begin with. The MC12 is pretty cool, though. I guess Zoxxy was going for more of the look of the F1 Ferraris while Darin went for a sort of FIA GT look. I think Darin kind of went all-out- picking its racing counterpart rather than the base Enzo. Zoxxy made the Enzo more aggressive with more lines and louvers.
My overall choice would have to be Darin, but only slightly. The dark blue is nice, but it takes away from shading. But I'm not one for little details, so I'd pick your car over zoxxy's. But both of you did very well. Hell, I'd say you both win.
