The following full and line render images, show how the scene was composed. You have to calculate every little detail, from the small stones that bounce when touched by the character when falling, to the blades of grass that grow throughout the ground. Everything that is outside the frame, behind the camera, is not worked out. Note how the building facades in the background have been created from a simple plane with many polygons, which has been deformed with a displacement map designed to obtain depth details in windows, doors, cornices, etc.
