You atleast know how to punch...
I do have to say though that you are pretty
stiff. remember that you don't have to hold everything.
Keep in mind also to not relax everything, either.
Try to keep a healthy balance.
Also, Don't try to do all your moves in one frame.
visualize what you're going to do. Some moves require you to
move in a direction that might not make sense at the time, but the next frame
or so, if modified, will help. Sorry if this is a bad explanation, I'm not good at it.
