More hair, less vegetable oil

I've been concentrating on the left side of the head, trying to take the hair up to the same level of "first painting" as the forehead. The construct of the hair also needed to be trimmed to make the shapes smaller on the left... Fernando noticed the open jar of vegetable oil I had on my stand. I had been using it to wipe brushes clean before switching to another value -- but this was putting the oil on the canvas! The vegetable oil should only be used when ending the session, and be rinsed out of the brushes with soap and water.



I'm also trying to construct my own neutral value scale, matching the Munsell example Juan posted on a pillar near my easel. His example matches true neutrality. It places pure black at 0 and pure white at 10. My own black paint (Ivory) appears somewhat bluish and all of my first attempts up to 5 were too blue (cool) and needed more brown.
