This work is unique because it is a perspective with people in it. The value of his piece is very bright and colorful. The main focus of the artwork seems to be the buildings and not the people. I say this because the buildings seem more intricate and detailed. It seems as though the people have not had as much effort put into them. The vanishing point seems to be the back on the cathedral. The horizon would be where the ground and the bottom of the cathedral meet. The orthogonals are the lines on the ground the people are standing on.
