I was also watching the ending when the guy on the left is knocked over.
I think he needs more time to fall, it almost happens too fast, and it doesnt have the impact it could have. I almost watched it the first time totally focused on the center character, and barely noticed he even knocked anyone over!
I see the hold you have on the left guy in mid-fall, and maybe you need to extend this before the final fall a few more frames.
And for the fall, after he is out of the shot, I think more of a take from the center character would make the fact he knocked the guy over funnier, because currently, the guy falls over so fast, and then the animation is basically over, so you dont even have time to take it in. When I watch it in slow motion, the hit is much more satisfying!
Another thing I noticed is right before the center character loses grip of the bottle, the final struggle is almost totally in the horizontal plane. I think you could make it much more of an interesting hit, if you would bring the bottle up around to the head level, so the elbows make a diagonal line, and also so the blue shirt character isnt blocking the center’s silhouette. Then when the bottle/hand goes flying it will have more of a arc as it hits the character
