The female orc is pretty neat looking anyway. Orcs in general have smoother animations than humans, for instance.
It won't look worse, but i assume it's gonna have more detailed muscularity because of the new textures and higher polygon number.
The real question for me is male human animated. How will it be possible to make it good and on par with the others without radically changing it?
I think i'll look forward to every model release, but, with release, i mean orc and dwarf/gnome. Not human or undead, these are just 3D models without even basic animations.
Textures will update the models and make them look really nice in the game world, but it's the animations that make them alive. Pandaren animations are on a whole different level then the rest of them, really, maybe with the exception of goblins and worgen. Not talking about aesthetics, but smoothness and "frames per second".
