Blocking In

Sometimes when I approach a painting I work one area at a time, finishing some details before moving on to the next area. While I did do some detail work in the background trees, I am mostly blocking in all of the basic shapes before I move forward on this piece. There will be a lot of detail work and getting the background correct is paramount. I don't want to put hours into detail work to find that I messed up a major shape. So for this piece, I'm working large to small, fine tuning as I go.
