Completely organic IG Growth

Hey so I'm starting to build up a personal account completely from scratch. I'm into visual arts but want to make myself a brand with a huge following in instagram. I know all abt botting & f/unf and that kinda stuff but i want to try to build my fanbase without that. So what are the best ways to build organically? Paid advertising? Shoutouts? I'm also having a little trouble locking down my niche. If you have advice & wanna see what kind of things I'll be posting i can pm you my @ name
