I think we all now by now that we need new animations . But some animations that would be useful are animations where we get a side profile of the characters. Say a character is dramatically sliding down the side of a door (clichè high school movie style ), we want to see their side profile. Or if an LI is holding the MC’s waist from the side, and you have an art scene showing this, then you want the animations to match the art scene.
Again, this is only an idea. I know it may be hard to execute it but I think this would take advanced directing to another level.
