Your replays sux.
I hate you.
GIVE ME SEX GOD DAMNIT.
MAKE MOAR.
But, yeah, the opener was alright.
However, once that grab stuck, all the momentum and flow you got from the opener suddenly stopped, then started again with that kick. This type of thing looks pretty bad and choppy. You always want to aim for smooth and fluid. (Like chamara said, don't relax too many joints. Try to use most of the joints you find useful to helping you get more flow, speed, momentum, etc)
About the two kicks, they were both at pretty awkward angles, and the transition between them was pretty generic. Meaning, bland, plain, unoriginal and whatnot.
ABOUT UKE'S NECK - Bad Ave, bad! No touchy touchy Uke in a ukebashing replay. >:c
But, yeah, you've gotten way better, but you have a lot more to learn.
