One thing you should remember in all your replays is that aiming is the most important pressing shift+space will allow you to aim much better and then the more momentum you have the more damage you can do and making hits look stronger and smoother is more just for looks than anything.
But I'd suggest since your just starting off to practise your aiming.
Mostly because in the beginning you should just focus on figuring out the mechanics and were to hit uke to get a easy dismemberment.
Hence the replay I've attached, especially in higher gravities, just hitting uke in the right spot is often enough to dismember him.
So your basically sying i need to stop swinging for the fences. I didn't know about shift space so thanks. Il try to do it when I get back home from school.
