Nice video.
I have been doing that in matches for quite sometime now. Again I like the effort you put in to it though. Keep going with it.
Up the damage with b2 axe after the first axe and then going for the OTG.
Also look at what it does on block. Its neutral so if your quicker than your opponent you can get off a d1 or d3 axe to catch them. or you could grab them.
