for some reason I never commented on the last pic in the previous post of yours... the b/w one with the model leaning back and looking over her shoulder.
Very alluring pose. A bit flat as concerns values... maybe you should try and achieve a bit more of local contrast on the parts which are not her so the soft gradations on the skin stay where they are.
of the new set I like #3 and #4 the most as they convey some sort of emotion on the part of the model which are not present in the others (rest looks a bit stiff - don't know why).
Finally, listen to purplerose (that goes for basically everything she says, but here I mean her "off-centered" remarks). There should be a reason for centering the subject. It conveys static balance, rest, peace, but also stagnation, stop, even confrontation.
One of your strengths is obviously your ability to capture the true person behind the faces, that is true portraiture.
really beautyfull work
