I should have taken a photo after the 1st session yesterday. Problem was it was so fragmented that I was all set on scrapping the picture by bedtime. In the morning, various solutions were floating in my mind. Maybe layer up tissue paper and paint over that; prime the page with gesso; wash over with burnt umber.
I did the latter while looking at the photo without glasses. It will look better with some skin tones and hair, I hope.
