For me, this isn’t a small thing. It’s a fundamental mistake that betrays a nearly complete lack of understanding about the character being animated. It’d be like if you were making a cartoon about The Flash, and the animators had him flying somewhere like Superman.

What is the point of this part of Rozemyne’s life? What is she doing? She is learning to be not just a noble, but the Arch Bishop and the daughter of the Archduke. She is doing this seriously because if she fails, it’s quite likely that her family and all of her commoner friends in the lower city will be executed along with her.

If you just have a two sentence summary of Rozemyne’s motivation like that, then this would never have been animated like that. It goes against her core character at this point in the story.

There are allowances that need to be made for animation. Like, in their society, nobles basically always either smile or have an otherwise calm expression, and never show other emotions on their faces, but that would probably not look good as an animation.
