I do enjoy the motion this drawing is attempting to capture! A comment that I would like to provide would be that of the chest, as the straight line could create a bit of a misleading broadness on the chest. One strength that you would be showing would be the conventions of the arms, as they show some of the active pull that could be present on the chain.

This is pretty good! I like what you did with the leg turned to the side, the guidlines show tht you were thinking about its 3d form. I recommend following that for the ribcage and boobs. Combining form with the line of action is pretty tough, but if you keep practicing it then youll make figures that are both dynamic and appear 3d
