Saharan Sunset - stage 2

Made a start on the sky including a decision to put in the sun as I want the maximum contrast tonally in the picture, from some near-blacks in the foreground to the virtual white of the sun. Managed to get two coats down of an Alizarin Crimson/Dioxazine Purple mix over the bottom of the painting through the use of Lukas Number 5 Medium that allowed the first coat to dry so quickly.
