In the comments, Sandy thought the pure color of the blue throw and jacket competed with the face. I took her suggestion to tone down the throw by glazing it with orange, the complement of blue, to gray or mute some of the blue. She was right, it does look so much better. This photo was taken inside this morning while the photo below was taken outside, yesterday.
After a critique by the Painting Friends art group, I made some changes by scrubbing out the neck and the gray lap throw and repainting them. I like the blue throw better but didn't quite get the look of Tim's chin correct. I also added more color behind his head in the dark area and along the shadow side beside his head and body on the seat. More color was added to the pages of the book as well. I'm calling this one finished unless the chin area bothers me so much I have to change it. *grimace*
