Sky and Clouds over Sauvie Island

It's been quite long time since last time I painted sky and clouds as the main subjects. I think the last one was "Clouds over Vashon Ferry" in 2004, which is decorating my kitchen wall. It was huge, about 4'x9'. This one is mid size, 22"x18". I was inspired by the shapes of clouds when I was checking the reference photos I took there this summer. Then immediately picked this to paint. The direction of clouds match the direction of green stripes on the farm ground. Stonehenge like isolated mass of trees in the center divides sky and ground.
