I began this abstract drawing with broad sweeping lines of yellow, moving into tan, orange, and shades of brown. Then I added thick lines in pale violet to emphasize the left and right sweeping arcs. Each step I take is based on looking at what I've got so far, quickly choosing what seems appropriate to do next.
I filled in some of the spaces with yellow squigles, then outlined some of the inner shapes with a fine line black pen, and finally used a fine line red pen to outline and fill in shapes. I could have kept going, but it seemed like the time to stop and let this drawing be. The yellow gives it a nice glow.
