Having a person (or in this case, two) was essential to the painting.
The balding head (the first one I have painted) helps the viewer see he is looking up at the painting. The angle of his bald spot nicely works with the angled figure of Daniel.
The woman completes the story. My first goal was to have her blue coat stand out from the blue couch. I debated whether to have a different color, but this combination seemed to add a pop to the foreground without being too distracting.
