That's actually a good idea because the game is a beat em up like smash brothers so I need the arms to move independantly
updated animation still doesn't address the shoulders not moving issue. there's a reason the shoulers move, its because when you run or even walk, your torso twists laterally somewhat. when your torso twsts, your shoulders move with it. if you tried to run withtou moving your torso you'd probably fall over.
Also, i'm not really fond of the walk cycle being almost a complete 1:1 recyling of ben's character's movements.
It might help to use a real-life reference, or something that starts off less stylized, like that which is located here
