The rims are butt-ugly on that car.
All of them are unclean, they have a jagged look to it, and they look sharpened too much.
They're all bland, there's nothing that catches your eye.
And on some pics, the grille looks like it was part of a TV without a reception.
And resize them yourself, if you use ImageShack's system, it messes them up.
Long story short, they're okay, I guess. They're not bad, but they're not good, either. I've seen better from you. Try one of the tutorials that's stickied, they may help.
