the run looks very heavy, almost like a fast paced march, not like a run at all. the swing of the arms is linear, no acceleration or anything.
the legs seem slightly too long, limbs are generally too thin, and uniform, and the knee joints are far too low in most frames.
You went several steps back from the previous posts i feel,
I'd suggest to study wolfies edit again, see how it looks fluid, running, fast paced, and understand why. Think about the kind of run or sprint you want, and look at references.
To be honest neither of the animations in this thread look like sprinting or dashing, more like casual jogging, but wolfie gets closest to a correct looking runcycle regardless.
i hope it doesn't sound too harsh, i dont wanna discourage you. Keep it up!
