Perspective drawing, cast shadow, and value assignment practice. 1-2-3 read from How To Render by Scott Robertson. The cube's natural value is 50% gray. Going half way to black (100%) from there makes the shadow side of the cube 75% gray. The same rule applies to the cast shadow. Because the ground is naturally 80% gray, half way to black is 90% on the ground shadow. The wall is 20% gray so the cast shadow is therefore 40% gray.
