I got to see some of the most amazing cloud formations while finding a place to paint this afternoon. I love the stacking silhouettes that these make against eachother. This one was done fairly quickly, so I was able to keep the graphic character of the clouds themselves. I contrasted this against the more textured and painterly area of the green hill.
