ipad art

I just downloaded "Brushes" for my iPad, which is the app which David Hockey has been raving about. In the blurb in the app store, it boasts that art created using Brushes has featured on four different New Yorker covers. Anyway, this is my first attempt at using it... The black line was done using Indian Ink and a brush, then I scanned it and coloured it in Brushes. I would really have liked to be able to have a "select" option, so I could have moved the mouth a bit, but I couldn't figure out how. Maybe you can't...
