Instead of making your subjects big, like so:
…you can also make them small, like so, and surround them with “nothing much”:
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.
