I’ve continued with the work of glazing the sky so that the blue and orange layers now sit behind a transparent layer of white mixed with a little Cobalt Blue. This makes the sky vibrate over areas of warmer and cooler colour, as the real sky does in the early morning or at twilight. I used a balled up rag to pounce the paint, making a smoother finish than can be achieved with brushes. Finally, using Foundation White, I brushed in highlights to the tops of the clouds, then pounced the white to make soft, wispy edges around them and softening the bottoms.
Finally, and very hard to see in the photo, I’ve added a little patchy white to the landscape here and there, just to make the surface feel a little more irregular.
