- try not to slide the foot of stickfigures all the time, animate clear footworks for most part. - weird choreography. things like tripping, especially when characters trip on their own is weird and doesnt worth the effort to animate. - have clear direction of action. EX: left hand punches, right hand goes the opposite way, body leans foward. All as they punch. nothing change direction until the action is done. Otherwise the limbs will jiggle - the black dude overeacts getting punched. If you watch any well done fast hand to hand sequences, you will see that they stay close to each other and doesnt get blown away by a non exaggerated punch. ( to put simply. Dont make the character thats getting punched blow away far if you want him to keep getting comboed ) In your animation the first punch blow his head back but he jiggles back weirdly. Probably because you dont want him to go out of the canva. which bring us to the importance of camera movement. Keep the fight in the middle of the canva - punches shouldnt just pass through enemy's body. Unless youre animating a video game or a dramatic speed blitz
