Next, I paint the general shape of the palm tree. First I mix alizarin crimson with a little dioxazine purple. Then I sketch the scene, establishing the horizon and the lines of the palm tree?s trunk. I make dots where I will place the ends of the leaves and connect the dots to create the palm?s shape. I finish blocking in my basic shapes by adding more purple to the crimson mixture and painting the darker areas of the trunk, the leaves in the bushes, and the shadows below the tree.
