You should avoid using Chest rotation while running and focusing using your Pecs to counter-balance while taking a step, in that way you can avoid having to much momentum in one way that can ruin your balance.
Using your Glutes more often, instead of using Lumbar can also make your steps more balanced. Be careful using it too wide/narrow, this is more of a shift+space move to center out the steps.
It's a good thing to see your tori "half-relaxed mode" while executing some moves or running, too stiff can look weird and also lock up the movement. Some relaxed joints can create a more stable move vs more stiff / held joints.
But part from that, good and solid moves, there's always improvements to be made, but you got the solid moves to use! Keep it up.
A reminder, add the mods you used so we can download them aswell and see the replay! (:
