Looks good to me. Very fast.
But would be more easy to judge if you hit something. Like a bag, bob, or a training partner
that doesn't matter this move is just to mesmerize the opponent. when they are standing there drooling with question marks and little birdies flying around their head then you really hit them.This is also my answer.
Until I see and hear something land we can't tell if the extension timing is correct or recovery will be balanced.
