>>1781639As far as I can explain it you need to worry about gravity when you draw characters.
When people move their torso controls most actions. It's generally the center of gravity unless other things are affecting it. Legs take over in the air when the character is in control of their action. If they're being thrown the torso goes first with everything else trailing behind. The arms only take over when they're in control of a considerable amount of weight.
A good way to look at 2 bodies acting upon each other dynamically would be to study people dancing. Studying athletes works as well. Look at how the and where they throw their weight when they make motions. It helps to look at videos instead of pictures. The difference between a stiff pose and a dynamic one is mostly how much the weight is affecting the body.
