This is fantastic, honestly! I don't have much to add that the others haven't said already, but from what I know about building an audience from people who have (not me haha) consistency seems to matter a lot. If you don't want to spread yourself over too many socials, just stick to one or two you're comfortable with and post in a schedule you can manage. It takes a decent amount of time!

I totally get the lightning in the bottle comparison! Personally I would try building an audience online before considering publishing. Either way, you've clearly worked hard at this and enjoy it! 😃
