Finally, I resolved this problem

In October 2016, I posted this painting in progress, incomplete and still on my easel at Three Sisters Islands. There was something about it that kept my interest but also bothered me. I finally figured it out this summer when I stood closer to the rock and studied it. I needed to paint the transparency of the underwater part of the rock. In one minute in the studio I added a few drops of paint and it was done. And I like it much better.
