I had no preconceptions before I started drawing lines for this composition. The first line was the curve that is now adjacent to the yellow-orange color. The next was a wide check-mark-like line that defined the space above the first curve. I like my broad-tipped dip pen. It is a bit old, so sometimes when I draw a line with it, freshly charged with ink, it sputters a bit, giving the appearance of a watercolor dry-brush stroke.
I echoed the first curve with a broad curved line underneath, and isolated the shape between with moats of gray.
I drew short stabs of lines and repeated them in negative space in the middle of the uppermost moat. I created other visual elements with a combination of in and masking frisket.
I like this design.
