Draw a simple scene that contains a horizon, a rectangular "floor", and two people standing on it. The floor measures roughly ´3 m´ by ´4 m´. One corner of the floor is closer to the observer. The two people are at different distances from the observer.

You get full points if what you draw looks "plausible" (meaning you can construct the scene using vanishing points or just eyeball it).

For extra credit: Draw the scene from the viewpoint of a kneeling observer.
