I'm not good at drawing from imagination, so I started with a fish. Of course the other two I figured should be fish as well. I used Toby's idea of grass to unite the three. Now that I look at this, the blue on the third fish really stands out too much. It would have been good to use some of that blue more in the first two fish. I'll make more of these and watch for that "unifying color" aspect. Fun stuff.
