depends how in depth you want to go. looking at gesture and force, anatomy, shape, 3D space accounting, negative space and simply looking hard are all steps in drawing poses accurately.
Personally a big stride in me pose drawings was taking notice of the gravity downwards, or rather how the gestures and flow of the body collided with the ground, made the poses look a lot less stiff and a lot more meaty and accurate.
Though if those are your sketches you're already doing pretty well.
