I noticed in the Alpha video posted on Facebook that both priest and swordsman units are having some very unnatural animations, especially how they breathe. Only people with severe health problems breathe like that. Skilled fighters breathe without moving their shoulders up and down. It's important for both close-range combat (attacking while the opponent is breathing in has a good chance to decide a fight), and for long-range units as well (difficult to aim with a bow or a gun if your whole upper body moves up and down during breathing).
This kind of animation is not disturbing in case of monsters, as, they are not natural creatures. But the above guidelines should be true for most humanoids.

I'm sorry to bring this up, I know it's a minor thing, and maybe I'm the only one for whom it's disturbing, but I cannot get over it.
