I think what E-Man was looking for was an anticipation frame. Note the second frame pulls back even further, making the animation look a bit smoother while also adding the illusion of force to the swing. I also changed the legs because they jitter around too much the way that plays.
[EDIT]
I changed the mouth so it doesn't open into a rectangle. It just looks creepy when it's like that, like a mad puppet or something.
