Need critique on my animations

So i make Animations for skyrim and a lot of people say that these animations feels too stiff, and i don’t see it, i try to make proffesional looking animations, also the second attack is a bit laggy, i gonna try to remake it today. also the .blend files with this animations, yes, this is exactly the same animations because skyrim love to mess with stuff2hm_attackleft.blend (3.7 MB)
2hm_attackright.blend (4.6 MB)

From what I could tell it looks like the torso doesn’t have a lot of movement. That back stays too straight
