I showed the image of the old man I posted yesterday to Ron at Wednesdays class along with a reference photo I had of a John Singer Sargent painting - Old Man with Dark Turban. I told him this was the effect I was after in my painting. His suggestion was to copy the Sargent painting. I learned a lot from this painting and in the end, I was pretty happy with it. It is oil on toned canvas board (11"x14").
