I darkened the sky yesterday but stopped as I didn't like where it was going and left it alone to look at the next morning to see if I could resolve it in the cold light of a new day. I decided that it needed more blue in the sky, to make the clouds more variable in colour and to get in the sunlit mountains on the horizon. So I changed the sky near the horizon, put in indications of sunlight on the far mountains and then put in an indication of the sunlit land in front of them. I need to fix in my mind how the lighting is meant to work in this picture so I put in more darks into the foreground before I start on the background palace buildings. This is quite a difficult picture to paint as it relies so much on the lighting and colour to get across the atmosphere I want.
