That’s not bad, but it does look a bit ‘mechanical’, which I know as a walk cycle can be a little hard to avoid, but it’s still very ridged with no real personality or attitude.
One of the bigger problems is that the upper body pretty much doesn’t move, it doesn’t rise or fall as the feet are furthest apart or lift back up as one leg is straight while the other passes by. Basically, it has no ‘bounce’. Also, the hips don’t move at all, it’s like only the upper leg can bend forward or back, with no counter dip/rise between hips and shoulders.
