Topless - stage 3

Started to work on the sky where I want the lightest part of the painting to be, the bright orange strip running between the sky and trees. I also used some Manganese Violet and Viridian for the line of trees to establish more darks so that I can tonally hang from this for the rest of the painting particularly when I have the trees and orange sky finished for my lightest light and darkest dark worked out.
