I haven't had the chance to even do it these days. I'm too busy working on photos or the like. I used to sketch quite a bit, in fact. My instructors liked to remark that I had a good hand for it, although I never liked it since I sucked at proportions for quite some time. I think I got better those years afterwards, but I haven't done it in years, so technically I guess I quit it already, although I might start up again if I go somewhere with a sketchbook instead of a camera.
