Hi...
Unfortunately there are many issues with your character including wrongly positioned bones (knees, elbows in the wrong place), but the main issue is that the left and right arm bones and sprites are reversed. For example you have left arm sprites on the right arm bone and vice versa.
To better understand how character creation works, I would advise starting with the most basic setup which is with a 6 body part character.
