Man, I need to get some color up here. This is a little sketch from a project I'm currently brainstorming on. I'm also playing around with a spiffy brush pen I picked up the other day (a Pentel Pocket Brush to be precise). The brush is really flexible and a lot of fun to play with, you can get wildly different widths in your brushstroke as you can see in the cowboy's trench-coat.
