Below are some prompts and exercises to help you find an audience.
Review
Who are you actually hoping will see this? Describe them as a person, not a demographic. What are they interested in? What are they looking for?
Why do you want an audience? What do you want their attention to make possible?
What do you want your audience to feel, think, or do when they encounter your work?
Where does your audience already exist? What are they reading, watching, listening to, attending, discussing, or following?
Why should they care about what you're making? What are you giving them that they can't get from everything else competing for their attention?
Practice
Give Something Away: make something genuinely useful, entertaining, beautiful, or interesting and give it away for free. Don't ask for anything in return. See who finds it, shares it, or comes back for more.
Make a Scene: take your work somewhere it doesn't normally exist. Put up posters, host a tiny event, leave something somewhere, perform it, project it, turn it into something physical. Find a way to make people encounter it rather than asking them to come looking.
Mirror It: pick one person or brand with an audience you want. Trace where their attention comes from. What are they consistently talking about? Where do people discover them? What makes people stick around? Map out what you find.
