First 'study' using Corel Painter

Wow, I should have picked up Corel Painter years ago. It has every medium from Crayons to watercolors and has a much more realistic feel than Photoshop. Well I just got it and here is my first study, I painted for 1 hour a deer skull. The layering and airbrush opacity helps a lot, though I have to work on my proportion and scaling a bit.
