Here's my attempt at an edit... it's pretty sloppy (note the accidental transparency
) but hopefully it brings the point across:
Hopefully that's what you were going for with the hair... I think perhaps in yours it's a little to conservative? As in, it only changes in a couple of frames and when it does, only subtly, then it snaps back into place for the next frame. I prefer to go too extreme and then have to tone it back. Should be pretty easy to accomplish if you're using graphics gale with the onion skinning.
I made a couple other changes too - for example he jerks all over the place - I put a horizon line on mine to show you what I mean. If he rocks forward and backward like that, when he's actually moving he will appear to have a stuttering speed - maybe that was intentional, I dunno. Also there was a lot of inconsistancies in the size of his feet, and there were a few frames where his feet don't actually move, but they change shape. That was also adding to the herky-jerky effect. There are some other subtle differences too but I'm sure you'll notice them yourself.
