While not a total confirmation, I would say I've only had to draw certain poses. For example when I drew the scene where the main character of the prologue was sleeping, I definitely didn't need a model sheet for that cut scene.
This next segment will be tricky, but I think I can manage it: I'm suppose to be drawing where the main character slipped and fall off the railing, and the main character's then girlfriend tries to catch her wrist. This sets the stage for that person barely surviving falling off the sky city.
For an example of a similar cut scene, imagine what: Spoiler:
Yoko in Battle Angel Alita would have been drawn like, as she was being catapulted into Earth's atmosphere.
MC's fall isn't that drastic, but it is suppose to set up the following plot as them barely escaping death, and living in mortal purgatory.
