the motion blur on the uppercut doesnt make sense. and the final stance is more like he's on the tip of his feet trying to reach something.
on the punch, somehow x's arm is way too elongated. its just like he just extended his arm expecting someone to crash agaisnt his fist. it has no movement from the shoulders, no effort, no nothing.
are you aware of how choppy the spining kick animation is? it needs at least a few more frames to make it looks smoother.
and the last ones are horribly blurred due a cheap rotation.
