Running and Walking cycles: are they smooth?

[Bearded_Beast]

on the legs, i think something is lost, because from 4th to 5th frame, his right leg moves from the front position to the back position.
on the arms, the 5th frame is moving forward, but the 6th frame is a backwards position

and the bandana should have secondary animation

Alright, guess I'll have to reorder the sequence. Do you have any suggestions on what could help me (ex. tutorials, programs, etc.) to fix the issue?
Also, which program did you use to animate it? I can't find one that doesn't put a watermark across the middle of the image.
