The initial painting was done with Ultramarine Blue (some color lifted for clouds) for sky and the farthest trees. Permanent Green/Quinacridone Nickel Gold mixes of different ratios were used for the trees and grass. The shadows were done with Ultramarine Violet and Quinacridone Rose and mixes of the two.
Then I mixed some Permanent Green into the Violet/Blue mix and added a glaze of it to a few areas of the main tree, and to darken the background trees, as well as the shadow running across the ground.
Overall, I thinking I did what was needed without over-fussing. Score one for me!
