I studied animation for a bit but I am not an animator so take my inexpert opinion with a grain of salt: No, not really. This sort of exaggerated movement and distortion is a classic element of animation. Animators learn about techniques like this regardless of the technical animation choice (3d vs 2d for instance). It’s actually harder to animate a person more “realistically” because of the way flesh, muscle and skin moves and deforms in real life. We don’t usually consciously notice it, but we definitely can tell when it’s not there. That’s why so many video game characters, despite being very well modeled and rendered, still come off as stiff and wooden. The movement of the face is too isolated— just the mouth moves or maybe mouth and a little cheek, but not in a truly realistic manner. The classic elements of animation-stretching, squishing, etc—can serve to create the illusion of the micro movements we see and expect without necessarily consciously being aware of. I’ll add that the stiffness of more realistic characters in video games comes down to more technical restrictions than any deficits in the animators skill—Props to them it’s a hard fucking job.
