Generally, when moving, he grabing way too end of the shaft. And it looks really not good, at the very least, to me.
It would be looks much better if he grabing the middle of the shaft, just like when he just stands on, when and while he moves.
Kruber’s Spear:
Its charged heavy thrust pulls back to behind of the body way too much. It should be just set the position at the side of his body and just thrust. The difference between light attack’s thrust and heavy attak’s thrust should be like difference between the jab and a straight in the boxing.
It would be looking more natural in this way, imo.
