I was thinking about how I would like to do a more complete picture instead of a simple portrait so I may build a story around this face. Stay tuned.
I had enough saved out files that I put together this handy animated gif for your viewing pleasure. You will notice that a lot of the drawing is done at the painting stage. I try to get as close as possible with the drawing and nail the general parameters but I really kind of sculpt it at the painting stages.
