I worked on this for about three hours yesterday. I am always amazed how long it takes (sometimes) to do what seems like so little. Mostly I worked on the foot and the light in the lower left-hand corner. On the lower left I worked on the passage from direct light to cast shadow/reflected light on the model stand: substantial to insubstantial. Everything we perceive is light but what is the difference in texture (both in a tactile sense and emotionally) between light that bounces right back to you off a hard surface and light that floats, intermingles, dazzles while meandering back to the eye. How to paint the transition from direct to indirect light so that the viewer experiences that transition as a melting from one state of consciousness to another?
