So i noticed the running anims are looking a bit off, like stiff or something, i decided to play csgo and look at the anims there, they were much better, of course from a years polished game, but it helped me to know what feels wrong about sandstorm's, and its got to do a lot with the legs.
Looking at the legs and the way the torso is so stiff make the anims looks lifeless, but i see they are really doing some progress by how the main menu characters are posed now, i just wish the anims in game were like that, legs spread out, good posture and very natural movement.
