What Jal says. Also the head is a bit weird / male, because the hair looks like a beard, and the lip color is a bit unhealthy. The NO reds would work better I think.
Totally adorable.
The only thing that seems weak is the title part of the screen because the logo head is the same used everywhere in the same size so it looks lazy. Also, the type color is maybe not the best design choice. I would have chosen the green from the arrows for that or the brighter blues from the car's window.
Nice, I particularly like the menu/text areas, although I do agree about the main character's head being a bit hard to define at first glance.
