Skateboard for On Deck 7: Progress 3

I was a little stuck on what color (or colors) to make the toothbrush, so I started mixing colors I was already using and came up with this purple.

I'm not sure if I like it yet or not. It's a nice contrast to the yellow shirt, but something feels a little off for me. Not sure what. I do need it to be darkish so when I add the lighter bubbles later they'll show up against the dark background.
