At this point, I’ve done a lot more with the upper part of the painting, adding in the lock, stone wall and greenery. I kept the water splashing at left cooler and a little darker than the water at right, so as not to compete. I’ve tried to break up the large mass of trees at upper right, and I’ve added some sky holes in the trees at left. I’m using my box of Girault greens, along with grayed violets and browns for everything but the sky. Having gotten this far, I realize that this would, indeed, have been a difficult demo. It’s the kind of thing that is best left to the private studio. Too much picky detail!
