hm...that run looks pretty..hm contrasting with the walk.
after looking at many games, I have come to a conclusion, the games that tend to look best animated simply have the actions transition from and into eachother either smoothly or in a flashy way according to how often they are triggered.
your run is pretty different from the stance, is this run executed often? it looks like it should be something that you dont go to from the stance very often, doesnt transition very smoothly from it (it looks like a fightgame run, where you have to push -> -> to run so it's ok to make a big deal out of it)
do you run often in the game?
