Alot of the characters just look to clunky im not sure how to describe it. The textures seem to be pretty good but as far as the mesh goes I think you need to form them a little better to fit the body more. The animation you showed above looks like a free mocap I saw awhile back but its not bad, the only complaint about that is with that armor I dont think that character would move like he does. Hope you take this as constructive criticism.
