When is an art work done. With me it can be a long time. I always let my art set and visit it periodically to see what it needs further. One time I forgot I had entered a piece in a show and had changed It radically before it was accepted. Fortunately the show never materialized and I didn’t have to figure out what to do. This piece illustrates my point. After looking at it I decided it needed dancers. So dancers were added. I’m not the only artist who does this. Bonnard was often caught in museums doing touch ups to his work. When I was younger I would have an idea and get it executed and move on. Now I realize that work needs to be continually improved until you get it right. Artists are no different than writers in this respect.
