Get rid of the pictures, and it would look alright.
But seriously, i would tone it down with all the Anime/Japanese girl crap. While the images aren't exactly Pornographic, there still a little too much for a game that young kids will frequent, and it kind of makes you, the skin user, look like a sad git to be honest.
If your still insisting on using images like that, try and smooth them into the cars colour instead of just pasting a picture on, and spend more than 5 minutes on the skin.
