Apples: Getting used to Corel Painter 12

I just began taking a digital illustration course, and I have never worked with Corel Painter before! So I "painted these apples from life to familiarize myself with the program a bunch of the available brushes. As you can tell I was more successful with some brushes than others. I must practice! If you are like me and have not picked up a digital program before now, I would very much recommend Corel Painter 12! It is very intuitive to the artist who is used to using a real pen, pencil or brush :)
