>>39451674ORAS has full cutscenes with correct proportions, you do realize this? That image is comparing those kinds of cutscenes in SM with the overworld cutscenes of ORAS, when the overworld cutscenes of SM look just as bad with janky movement and the protagonist's perma-smiling face.
The chibi look is an aesthetic. If you don't like it fine, but it's not a fault with the game.
