In regards to the face in that picture, that is just one scene where the lighting wasn't too good on the soldiers face. Since the lighting changes as the players move around the level, they look better/worse depending on where you stand in the level. All of the faces now are 3d scans of real people's faces. You can't get any more real than that. But as has been mentioned with the Heroes system the faces will change over time, and look much cleaner when the player is a raw recruit.
In regards to the running, we motion captured a professional mocap actor (we used the same studio used for Avatar, and one of the mocap actors from Avatar). He ran the same way German soldiers were trained to run. And if you look at WWII photos of German soldiers in combat, they are almost ALWAYS running with their gun in one hand like that. So sorry if you don't like the way it looks, but its historically accurate, and realistic.
Yeah, its a good feature, but more variety would be better. As i saw in the trailer, there is only one runing, walking etc. animation in the game for each side, so all russian soldier are running in the same way, and all the germans too. In my opinion it does not look so good. So it would be great to see at least 2-3 different animations for each movement (running, walking, crouching, even weapon reloading, with the same speed, just with slightly different movements). My most loved feature in Empire: Total War that all of the units (thousands!) are holding their weapons in a different way, what looks way more netural and realistic. Dear Tripwire, pls make more animations! It will be worth!
And sorry for my english.
