My work is extremely loopy, and I've noticed over the past few years that I definitely have a tendency to make everything slant to the right because that's the way my right arm moves. Trying to balance it tends to make everything look stiff, so the best solution is clearly to learn to draw with both hands, and possibly also my feet.
I haven't yet done any finished art with my left hand, but I do have a pile of sketches I've been working on.
In other news, I just finished two zines, which I handed out sporadically at the Small Press Expo two weeks ago, and which I will be debuting at the Richmond Zine Fest this weekend.
