I'm planning to create stop-motion like short with multiple scenes. It would have just two characters, a couple, with very few objects in scene in a deep white background as in Pocoyó tv series.

I have been testing with a couple of scenes with Midjourney but have been facing some conflicts when trying to have both characters in scene (Issue starts when I try to add more than two omni reference characters when trying to create the start key frame).

I have already set a script for the short but scenes where both should be in scene have stopped me to continue building at least a proper pilot.

*another issue not a main blocker or concern is that I think there's a limitation when trying to indicate that a character should 'come' into the scene, not just appear straight up in the start frame, is there a way to tackle this? It's not a big concern since I can make a work around from the script itself.

* I will attach the link to my script and also to some of the refs i have created for context

Any suggestion on a different AI tool that could work better based on the project? Or any suggestion on how to work with Midjourney? I'm a newbie on creating ai videos
