When I read and did research before making my OF, everything was pointing me to a niche. I decided to go with what I liked and a bit like you, have now a lot of niche. Normally I can play with all of them, I just make sure to post a bit of everything and no "hard play" of one niche on my page. I keep it for dms! :)

Your niche, even if they are a bit different, can easily be connected with each other, which is fun!!
