I call this drawing, "Nude and the Yin Yang."
What the Yin Yang symbol represents belongs in many settings. And, it surely belongs in this setting where we find a reclining nude woman.
Unlike many of my other stylized renditions of nudes, this drawing doesn't depict a red-haired woman. So it represents a departure of sorts.
I created this drawing using one of my favorite media which is pens on 140 lb. paper.
