The Ramparts of Al Kazaar - stage 9

Something has been bothering me about the composition, the horizontal line of sunlit sand in the distance. I felt I needed to break it up with maybe a few small rock outcrops but I realised this morning that what it needs is that the shadow of the city on the rock outcrop should only go partway across to the left so there are now more sand dunes in the sunlight coming around the left side of the picture thus getting rid of the original thin horizontal strip. I try to avoid verticals and horizontals in paintings and try to give landscapes more movement by using lots of diagonals.
I also have made a start on the ramparts and buildings.
