This is my second shot at Corel Painter. Before a few days ago I have never used Painter before and now I am absolutely hooked.
Photographed by : http://rust2d.deviantart.com/gallery/ - this is a digipainting of the model Yana Ultra (view actual photograph used here: http://www.deviantart.com/view/21355202/ . I really wanted to see what I was capable of, as well as what the program could do. I paint traditionally and, NO I didn't 'trace' the picture.
I did however, flip the pic around though - just because I find painting faces to the left is easier... go figure.
I chose this photograph to teach myself tonal values, light and dark, negative space and foreground and background in Painter.
Being a photoshop lover, this program was easy to get used to once I had a few Lynda.com tutorials to help me with my way around.

Done entirely in Corel Painter.
Approx 20 hrs of work.
