Here are a few examples for you:
The one with color is an example of how I use the second one to the right (top row) and the bottom left brushes. I use the one on the bottom (the solid one) with one color (a light color is usually best), and then use the one on the top row on top of it in a different color. You can get some really interesting effects that way.
There are seventy-five brushes.
PLEASE comment and credit. I'd like to know if anyone gets any sort of use out of them.
