It's very floaty and the head turn is strange. (He's looking forward and then to his right, but never to his left.)
Head turns in running animations are generally kind of weird anyway, because no one actually turns their head when they run. But a lot of game sprite animations seem to use it for extra effect, so I suppose it's not that big of an issue.
Its terrific but its running rather slow on my comp :/
So, that's a cool animation i love the smoothness in it.. but the head turns far to the right.
