Meh.
You should really look at other stick figure animations and possibly try to mimic what they do until you get a better idea of how to work it. The animation is, at least in my opinion, sloppy and not very smooth. Be sure to use tweening, it really helps smooth out the odd jumps animations can have.
You also may want to work on your realism a bit... that poor guy bending back at a 90 deg angle must have been in pain... even for a stick figure.. o.O;
