I really like the blueish gray that you've used here. I'm not particularly fond of the yellowish tan though, I think it may be too saturated. Perhaps its just the mixing of warm and cool colors, I feel like she'd look nicer with a more uniform pallette.
Switch! That's a cute name *3* I like the color scheme that you're going for--but it seems like it could use a little more contrast? Perhaps making the tan slightly lighter and more saturated (juuuust slightly) would balance things out a bit. Just my two cents! : )
