OMG! That kick was absolutely FANTASTIC. It looked so real too.
Perhaps you should retry this kick with fracture on to make it even more realistic.
Also, try this start with a larger engagedistance and somehow run towards your opponant, jump into the air and kick him with your feet in the chest, side-on. Sort of like a bullet.
EVEN do it the other way around with your feet, so it looks like what Neo did to Agent Smith in the Matrix (the last few scenes of Matrix #1 I think) How he runs along the corridor and JUMPS into Agent Smith.
That would be some entertaining replays to watch.
Keep it up.
