I spent most of the last week working over the rocks, a day on the grasses and minimizing the outlines of the columns, then two more on the sky and the tree. I'm happy with the overall dark-light pattern of the loose rocks and how it angles up and to the right, curving slightly around this end of the butte.
The most interesting thing that happened was a disagreement between me and the bottom left corner of the sky. I wanted it to be dark clouds, to match the upper right, but overnight I realized that made the whole left side look as heavy as the right, and dragged down the energy of the whole painting. The next idea I had was to turn those clouds into lighter, more bluish shadows—but as I worked on those, the whole small area turned itself into light sky instead. As soon as that happened, it made the white clouds look even brighter, punched up the green of the grasses, and for some reason made the face of the columns stand out more, both in brighter values and also in a dimensional sense.
I was so taken with that brightening effect that I invoked my artist's license to delete the bare tree growing out of the butte face on the left side (sketched in, in previous versions) so it wouldn't detract from the vertical lines of the butte. My excuse is that 100 years ago, that tree would not have been there, but the butte and the rocks, and probably the grasses too, would have looked the same as they do now.
And I got just the spring color combination I wanted!
