The distant background has cool tones and as I move to the foreground I will add more warmth to the scene. Right now I have about 6 brushes which I am using. Flats are my favorites, especially ones with an angled edge. Those work particularly well for a subtle defining of the trees.
Even though my easel has been modified to hold the board, I can't paint this upper area sitting down like I usually paint. The top of the painting is still so high I have to reach up to paint certain areas. I am walking back and forth and spending a great deal of time standing back from the painting. On a piece this large, you just can't take it all in unless you are a good distance away.
