A quick 15 min charcoal study for a painting i'm working on. After many many years, not since school really, I picked up willow charcoal again. I've found it especially useful in art class doing life work.
I normally steer clear of this stuff as I get into such mess, but i'm finding how invaluable it can be. A bit like working with ink, with anything other than a pen, you loose a little control, you can't fiddle. I've found this way I experiment more. Working on this gave me other ideas for the bg as well. You really have a freedom with this stuff.
