Its ok..
I mean, there aren't as many options as there usually are in games of this type, but I do like the "add your own decal," feature. I don't know if I just couldn't find the button in the menu selection, but it would make the game more complete if you could first change the color of the actual car, and second, change the background. And remember, as the game gets more complex and starts to have more options as you tinker with it, it would be a good idea to have an instructions screen on the main menu. Good luck in the future. Keep working.
