You never cease to amaze me with your originality. Such a simple subject that nine out of ten photographers will just walk past it, but you have transformed the grass, the paving and the shadows (of two different densities) into an abstract painting by doing nothing much -- other than shooting a tightly framed composition in which the tension created by the perpendicular and the tilted lines is offset by the assymetrical balance of the light and dark areas. Great work.
