I've been having fun doodling with this technique, but I wanted to see how refined an image I could wind up with if I took time with it. If you want to see a bigger version, you can download the full-size over on the bar at the left. I didn't have the heart to shrink it too far.
This is actually from a scene in our Star Wars game, when the Force Adept and the fallen Jedi fought over an evil book in a suitcase. They kept throwing each other off platforms. It was a very acrobatic fight, not communicated particularly well here, but I hadn't drawn the crew's traitorous ex-ally in a while, so I figured it'd work as well as anything.
There's vague city-type stuff in the background because it looked too bare otherwise and I couldn't be bothered to do anything significant.
What I really like about this style is how much it helps me with lighting. I know my black and white art tends to come off looking kind of flat, because the subtleties of ambient lighting have long eluded me.
However, I have also recently stumbled upon a technique for creating more dynamic poses. It's the simplest thing in the world, and I can't say I invented it, but it sure works well for me: you just draw a line, and that becomes the basis for the character's pose. I'll describe it more in my journal on here, if someone's inclined to check it out.
