This was done in the last 10-15 minutes. Just the keyframes, I'll go in and add arms and a head, as well as more frames to make it smoother.
But hey, it's progress over that last one. I think what I was doing wrong was that I was using noodle legs, whereas it's much easier to make it look natural with straight lines.
Oh, and ignore the random messups with the lines. That was from converting it to a .gif.

Edit: Updated, I don't think I'm going to add arms to this one.
On to the next practice!
Edit again: Ah bollocks, I forgot that gifs don't accept movie clips. Just take my word for it then, the dust that pops up after he falls looks fine.
