Homebrew Campaign

I am currently working on a Jujutsu Kaisen based homebrew campaign. Any tips? I have already made the homebrew class and subclasses that the players wanted. (Ten Shadows, Limitless, Star Rage, Ratio, and Curse Manipulation.) And have already fixed balancing issues with some of the cursed techniques (Limitless) We're going to have our first session soon enough, (After I plan it out) Any tips? This is my first fully homebrew campaign, but i have worked with homebrew in the past.

1. Don't worry about mistakes. Embrace them. It's the best way to learn how to do better next time. It's okay to admit to the group that something is wonky, and to talk about how you will fix it. Number one rule of DMing.

2. Don't over prepare. At most, plan for two sessions ahead. The PCs are liable to take things in a totally different direction, and it's better to not waste prep time on something you won't use. I just follow my characters as they progress through my story. I write down who the current protagonist is, what they want, and how they're going about doing it, then I incorporate that into my game as the players follow whatever means to beat the villain that they conceive.

3. You're a player too. Your fun is just as important as everyone else's at the table. 

Thank you for the advice! I'm very excited for this campaign, and I really want to see how my players use their subclasses (techniques) uniquely.
