I'm not used to seeing that type o' stick figure particularly so it looks strange to me. However the animation was a tad too quick to actually understand, and also the kick at the end, the sticks leg is extremely wobbly. The arm stretches when the punch is thrown and he recovers from the punch a bit too quickly.
Looks a tad like my old style. Peeps here are getting better. I didn't see much impact and anticipation. So, the force was gradually weak as the kick was too.
Other than that, work on your anticipation and your good to go. Try not to post such short animations. Btw, making a tribute anim for the king.
