When I draw on the bus, I have to be discreet about it. I don't want someone to come up to me and challenge me to show my sketchbook. So I draw a snippet here, take a glance there, and rely on my memory to fill in the blanks. I like this drawings, because it means working around a few core sketches, and adding details that will be meaningful but not detract from the whole.
