This scene is lacking any sense of depth. All the sheep are the same size, which makes the cell look flat.

By cropping the man and bringing him to the front, he is made the focus of the cell. By then varying the size of the sheep as they go farther back, there is a sense of distance created. Layering the sheep adds to this effect.
