I’ve painted in the background and the shadows and added a bunch of small specular highlights. Overall, the larger painting size has been a good thing and made painting easier. The only challenge is that I haven’t been able to work wet into wet quite as much as I’d like because each painting session takes so long. As an example, I painted the green shadows one day and when I came back a few days later to do the yellow tabletop, the green shadows were dry so I couldn’t feather them into the tabletop. I will need to either do longer painting sessions or get good at touching up the soft edges after the fact.
My plan for the painting is to first repaint the red handles to better turn form and darken the form shadows while making the ends recede into the distance. Then I will, in one session, redo the green shadows and then darken the yellow background, while feathering in the penumbra where the green and yellow meet. After that the painting should only need small touch ups and a signature.
