well you did xD but....
that kick didnt see so powerful
try making the kick start from behind the body (in this case instead of using the front leg to kick you could use the back one so it could look more powerfull)
and try not moving the legs and if you make the legs move make the body move
and last one after the kick i think you should make the body like inclines more to the back

my tip is...
watch a lot of animations and when they do those movements you could watch them frame by frame "right click--->forward" and keep doing the same thing...
trust me it works xD there you could chek how long it took the stick to land or how much frames did the stick let his leg still after the hit

Practice my man.

try to link your movements better like it took way to long to kick
