I ike the game, I think extending the festival to a few days maybe 3-4 with intertwinning stories would make this a good long play, also maybe creating a specified lora to maintain the same character but changing the clothes would give it a really nice spice on attention to detail.
As for the voices maybe some more variations on the initial expresion would be cool. I would explore as well maybe using inpaint features for the faces to give the characters some more expretions as well! (emojis are usuable as prompts with a lot of models)
I'm working on a similar project so its cool to see otheres explaing the same route.
Stay safe you guys :3 really neat what you guys came up with c:
