It was all a bit complicated.
I wasn't sure that it was possible to control myself. The lines, and dots, and circles just keep coming. It was a deluge. Now that I can see it; I'm glad. Losing control, letting the energy of the moment take control of the drawing is what I seek. The energy can be quiet and rhythmic — obsessive or unexpected and overwhelming. It's all good.
