You know how you wonder why a painting isn't working, but you haven't been able to figure it out? That's what happened to me with this painting. My eye kept looking at the handle's shadow between the two front tomatoes. That became my center of focus, and in fact I wanted it to be the cup.
After reading Richard Scott's book Sketching from Square One to Trafalgar Square I asked myself what interested me most about this still life? How do I emphasize the cup and deemphasize it's shadow?
