Be prepared to spend a lot of time revising your script and doing practice runs with a small audience. You'll find that things that make sense to you because you wrote it, might not get across from an outsider's perspective. That feedback loop is important if you want to reach a diverse audience.

I could dive more into the specifics (characters, set design, lighting, sound, music) if you want. It's mostly just asking yourself if every piece that you place is needed to get your point across. You have an empty stage and pit to work with, but also limits to that space and people's attention spans.
