Ultra Patrons - Looking for Feedback regarding new tier perks!

Hello Ultra Patrons!
I wanted to give an update about perks for your tier.

As you might know, I've done 'Request & Animation' streams for 2+ years. These streams served as an anchor for the Ultra Patron tier.

This year however, I'll be discontinuing those to make time for new perks which will maintain the current value of the Ultra Tier.

------------

Currently, I'm thinking of adding in all of the following:

- Ultra patrons would choose which character is selected for future character Q&A's.
After original character's are exhausted, existing characters from movies, games, or similar can be used.

- Ultra patrons could take part in new OC creation, which can be done within a stream.
Ultra patrons can choose what sort of new character I make, what world or universe the character inhabits, how they may relate to existing characters, and similar. In short, you can have some say in worldbuilding and help make a new OC that will show up in future art.

- First dibs on "formal" commission slots.
I.e: when I do bigger openings for custom comics, illustrations, animations, etc. you guys would have the first opportunity to fill limited slots before patrons in any other tier.

------------

See...my issue is that the above 3 perks don't happen on a predictable timeline like the Request & Animation streams did. Hypothetically, a whole year could go by with only maybe one of the above actually occurring...

I'd like something that folks have a guarantee to participate in, if they want to.
So, I'm still brainstorming.
I'd like to have something solidified by next month so I can go ahead and start integrating it.

I'm open to suggestions and feedback if you have other ideas for perks.
I'd like to make things worth it to you, so let me know what you think.
