Honestly, I get more pleasure out of this when I don't think at all about trying to make a nice picture, and I just cut loose with a 2B pencil. It goes quickly and follows my mood and my pinballing attention. I can concentrate on a profile that I want to capture accurately, then I can scribble, responding to how a shadow or texture makes me feel. It's great fun. Sometimes I enjoy drawing much more carefully, but not today. Just like sometimes I like a neatly arranged desk, but this morning, scattered pipes that need cleaning and no place to put anything down suits me just fine. But I did empty the ashtray . . .
