Build something, or a number of things, that you think would cast a great shadow.
Take your creation to a sunny spot, inside or outside on a sunny day. Observe the shadow it casts. Move it around until it makes the shadow you like best. Notice how the shadow changes when it is cast on a wall, compared to the sidewalk, compared to the texture of a tree trunk. Where do you like the shadow best?
Take a picture of only the shadow.
