Charcoal sketches

I have been messing around with charcoal. And messing is the right word - fragile, powdery stuff that smudges all over the page, and about as easy to control as a feral cat. But I like the broad, painterly effects, and I'm thinking I should do a lot more. They seem to be a good antidote to my tendency to nitpick drawings to death when working with more precise media.
