first relax more
second don't just move random joints hoping for something to happen
If you mess up a kick you can always press "e" at the frame you mess up and fix it
Before you make a replay always press "c" so you can be at the relax state that's what i do.
Then press on joints but first know what your doing
I not going 2 rate because if i give you a high rating you think you're replays rule and i won't rate low either because you'll think you suck.
