When you see all three panels together you get an idea of what I am trying to do . . . keeping the colors consistent, and also making it look like one painting -- even while trying to make each panel a painting in its own right.
Here is a close up of the left section of upper trees. You can see some nice transition of colors, but it is still somewhat splotchy. I also talk to my students about "spottiness" and how not to break up the masses. There is a fine line between changes that need to be made and those that can be left to the imagination. So . . . I have totally wiped off this section down to the initial underpainting. It is now quite dark, but a good beginning again.
