Too much arm flailing imo and he should work on his left foot for heel juggling because its at an angle and not straight
do you practice lower yourself? 
Yes, but not stuff like skatw etc
i tell you bro his style is good
rocco (sickest lower style imho) swings his hands too - cuz that's something you can't avoid - if you practice lowers yourself - you must know that - try to do any twofooted nt - lets say amatw-amatw and record it
Im not saying his style is bad or anything, im just not a fan of it. You have to understand that not everyone is going to like your style.
but he should work on his heel juggle style.
