There are so many things you could improve on here for creators that it's actually kind of scary.

First things first. Content ID... you have verified models out producing content. How about ensuring that said content is actually protected.

Next. Fully modifiable metadata... Being able to change your tags, descriptions and titles is almosty essential given that you are utilizing a search engine. SEO should not be restricted to the one time fill in form when uploading a video.

OK, next. Categorization for friends.... It would be nice to be able to tag friends with a priority status so that I can view only replies and comments from those people that I have tagged. This is really just a QOL suggestion but it would make it so much easier to handle interactions with fans, followers and friends. Especially for people with thousands upon thousands of subs.

Next up. Customizable profiles... You know, banners, display names, a widget based page perhaps where you can choose what elements to display.

Next. A suggestions section.... I am a creator, I produce content and I also interact with other creators. It would be nice to be able to suggest some of those creators to my subs. A small section on the profile would be more than sufficient

Those are just a few suggestions. Honestly I could go on for hours given how janky and amateur feeling the site actually is but I'll just leave it at that for the moment.
