I felt like I was a bit too tight in my rendering with the clowning fish piece so I tried working looser with this one. I used the pencil brushes and watercolor brush I normally use and several paint brushes that I haven't use before. There are a lot of brushes to choose from in Infinite Painter and there is plenty of room for experimenting and exploration.

Clowning a Fish
I found several images of fish on the web and this one seemed to fit the bill. The image here is in process.
