Instead of making your subjects big, like so:

Moo!

…you can also make them small, like so, and surround them with “nothing much”:

Horses in Mono

We call that using “negative space”.

The use of Negative Space is a great way to show your subject not as huge, but as interconnected with, and inhabiting, a large area.

The negative space needs to be just that: negative space, i.e. devoid of meaningful content. It does not have to empty: just empty of information.
