Painted on a 12 x 9 canvas board. I am very pleased on the sky and am surprised how it looks. I originally did not expect the sky to look good at all. I probably should cover the left side to the mountain with a tree, but I did not see this until I had already added varnish to the painting. It is not as misty as Bob's, but it does have some and has nice depth. Painting this on a smaller surface was a challenge because I ran out of room towards the bottom.
