Probably took a bit longer than it should have considering the simplistic nature... but I'm a bit finicky....and in uploading it, I noticed another logo I can add to it from another pic that's in my album.

I think we should have a skinpack manager or something
First of all, your colors are too bright and saturated. The graphics renderer in your version of the game likes the textures to appear as a bit washed-out in Photoshop view.The blue colour in your texture is obviously the biggest flaw as it's way too saturated. If it helps as a reference, on Muscle01 the green car (#52) with a white top has those "Gaso" stickers. The blue on those are close to #254e9e. Also, you would do well if you raised the black's brightness by just a few percent higher to make it appear more worn and old as now the black areas of the car are crushed out (photographically) as well.
