This is my first time doing this but what should I focus with the stories I've posted?

Gacha Surprise?
Restroom Encounter?
Spencer & Eric?
Our Entanglement?

Gacha Surprise - It's going to be a pretty short series and my idea is to do two more parts (switching over to Danny's perspective) and a possible what if.

Restroom Encounter - I have a general idea of how to continue it but unlike most of my stories I don't have a clear ending for it.

Spencer & Eric - It's gonna be an on-n-off series with no real end goal but I do have the next part in mind and a possible what if.

Our Entanglement - I already figured out the ending (mostly) but how to get there is up in the air but I do have a good idea for the next part. This series is gonna be my longest so far and it will be some time between parts compared to other stories.

I want to get some feedback so I can focus on one of these because one idea for Mana Tools Inc. has hit me and I've been itching to write it.
