Here is the second Brushes painting on the iPad.  I was trying to learn how to use the layers so I started with peach tint layer then imported a photo of one of my drawings for the second layer and started painting.  Finally I added a third layer to deepen some of the colors.  I may get the hang of this after many more experiments and it occurs to me that I could use it to design Tapestry cartoons and even knitting projects.
