The light throwing radiating shadows down the steps would just add the mystery and bigness necessary for the subject. See more ideas about perspective drawing, perspective, drawings. It is evident that the sun being unseen behind us, we can no longer draw rays from it—as in the last example to obtain the length of the shadows. take lines to the marks on the ground, and continue them till they meet the ray above each mark.
