Agh im kinda played with it around frame 270. Idk if this is the result you wanted, I kinda forgot what i did exactly too, but i think i prep'ed the punch up a little sooner than you did while compromising a little bit of the rotation you was having from the left leg.

Regardless of the problem you was having i think that wip was dope, i really liked what you was doing there keep it up!
