Now, it is currently good and i prefer it over the vanilla character if that says something. But at the same time i can see there's something something a little bit off in the running animation, that i have hard time putting into words just what it is. Stiffness of somekind. A few comparisons:

How do they differ from gear girl? I suppose the other 2 sway more up and down, and back leg doesn't stay so far behind. Gear girl seemed to snap the forward going leg in place a little bit, braking the fluency.

I guess this is one example of how not to animate running :) But it looks similar in a way:

We could propably give better feedback seeing the high detail 3D model in animation. It's difficult from the pixelated one.

Thanks for the feedback, I'll try out making the running animation more bouncy and see how it looks

Did you ever get around to improving the animation? I think it still looks like her head is moving on rails.
