The anticipation pose on the yellow character with the hands above the shoulders is a little weird especially because in a few frames you zip them onto the shoulders. There's actually a lot of time where those arms are frozen in place and you're going into the anticipation pose. Maybe you plant the left then the right and go into the throw down.
The other thing I could see is the red character seems to hold their left arm back right before being thrown down, in fact the whole character is easing into that anticipation pose. It's making an effect where the red character almost seems like they're in on it. I don't know if that happened because you keyed out both characters together but maybe offsetting timing on that to make it look like there's more forces pushing and pulling the red character. Maybe the arms and head are all moving at different rates and hitting poses at different times because the character is dazed and being pushed around.
