I think the downward walk looks fine, but the side ones have way too much hair movement. specifically, instead of looking like its waving back and forth it looks like its trying to jump in front of her over and over. The movement on the side walks should be a lot less drastic (since your seeing it mostly from the side the movement would be less noticeable)

For the up walk try starting the swing from higher up on the hair or something. it looks a bit odd at that angle that only the bottom swings.
