Decided to expand my knowledge of other design software, so I started using Corel Painter 12. It is relatively easy once you figure out all the brushes and it is similar to PS with layers.
I like the way it can make painting much easier then using the conventional brushes by eliminating the canvases, mess and space. Don't get me wrong I still use sketch books and occasionally acrylics, but now I can produce more work with less stress.
