This is a writing prompt you can adapt to your own favorite mode. If you're a poet, write a poem. If you're a prose writer, write prose. If you're a journalist, write it like the opening or a piece of an article. Think of this as an exercise to work your muscles. So you can even use it as an opportunity to flex muscles you haven't used in a while-- maybe if you're a poet, write prose instead, etc.
You can also just free-form this as 200 words or so. If you're new to writing prompts this is a good place to start. Then if an incident in a story comes up where these descriptions are relevant you can plug in the prose.
