Quote - I think the difference is obvious.

Rigid hip was most unnatural part of body almost all poser figures. You all can you check it with mirror. People cannot bend legs more then 90 degrees (sometimes 80 sometimes 100) If you pull your knees to your chest you must bend your torso. Antonias hips are not only better, they are natural.

Another misstake in poser figures are arms. People cannot move arms up along Poser Z axis. Check with mirror ;) You can move your arm up only a little, later you must twist your shoulder. If you look at mirror you can easy notice, that, with arms rised over your head, your armpits are turned towards the front.
