Digital Drawing of Reclining Female Figure Drawing Model

Nice long 6 hour pose with a reclining female figure drawing model. Started with black colored pencil and then added both white highlights and reds in the shadows. She was laying on a red sheet with some strong overhead light so that red reflections in the shadows were really strong. Would have actually liked to keep going. Felt like I was able to keep going into the drawing without leaving it looking overworked.
