I may have lost some dark values in the hillside to the left under the cloud shadow. I will most likely repaint that area along with the larger hill on the right side. I think placing the trees on the left foreground in shadow helped quite a bit. I made the patches of sunlight on the hills more prominent and totally reworked the sky. I'm not sure the sky is an improvement over what it was but its not a focal point and should not draw to much attention in this piece.
