Thinking about painting digitally

I've decided to start working on character pieces from my favorite shows on Showtime. I'm not sure if I want to paint them traditionally or digitally or both. So I took my sketch of Leiv Schreiber into Photoshop using a new brush called Stumpy Pencil that a coworker told me about. I turned it into a blue brush and threw in some sketchy marks over the top of my existing pencil sketch and I actually like the result. Now to paint it. That'll be the next step.
