Thanks guys
The car may be a little bright (I've also recieved a comment that it looks a little too sharp) but the whole image has a hue adjustment and brightness/contrast adjustment. I think the reason it looks brighter is because the hue adjustment is overtop a (mostly) bright yellow car verses a darker background.
I think it may be a little too red as well, but that's one of the major problems being sorta colour blind. :P
Thanks for the comments guys. I might tweak it a little and post a second version. I made this for my new Walpaper, too. Too bad I only grabbed the pic at 1440x900... it's too small for my laptop desktop. haha
