It's not enough to just use the same keyframes from the low res to high res and make linearly spaced in-betweens. Especially since there's a large difference in approximating movement between the two. What you should atleast be doing is making in-betweens based on timing, not object spacing. The animation is very stiff as a result. Every movement is too linear which makes him look very robotic (most noticeably in the 'smoothest' walk). Everything changes momentum instantly. Things need time to accelerate and decelerate. This includes the hair which also seems to 'pop' from the lowest point to highest point. Knees/feet and arms/hands swing forward during a walk/run instead of "keeping up" with the upper leg/arm which also results in stiffness.
Besides the animation issue, I think the mid res smoothest is moving too much given he's only walking. It looks more like a jog to me. Maybe in-game it'll look fine?
