This portrait sketch is from a portrait session last week. It was fun painting someone who has "Emmylou Harris" colored hair! Oil paints used were yellow ochre, cadmium red, ivory black, and titanium white. I never use a medium except to occasionally thin paint a little with odorless mineral spirits (OMS). One of these days I'll try experimenting with different mediums, but for now, I paint without them.
