This step may appear dramatic. Simply put, I mixed Cobalt Blue and Alizarin Crimson to create a violet, heightened with a bit of white and the Vermilion/Yellow of the sky applied the back-most land masses. Then progressively lowered the value and added more blue for the middle land; and finally more blue and Alizarin for the closest islands in the middle-ground.
I further took the violet mixture and dropped-in what will be the misty water masses created by the falls on the left and bottom of the painting. With a thin veil of the same color, I lightly went over the right side of the sky and water below. I had to work quickly to maintain a painterly look.
The paint at this point is still very thin. I did not want to commit too soon to the shapes and arrangement. If this had been a regular shaped canvas, the composition would have been easier. As you can see, the palette thumb hole is the greatest challenge facing me since I have a round sun to contend with. The paint will become thicker as I apply layers so have left the sun area white for the time being.
