#3 is well done, i liked how you were able to balance out the lighting on both her eyes even when having to deal with the shadows.
but somehow the highlight created by her top and also, the curvature from her chest (the 'valley' if you want to call it) in my opinion could have been covered up as it drew attention away from her face. this is because the lighting is more pronounced on the lower region of her body, and so careful composition would be needed to retain the viewer's attetion on your intended subject. my 2 cents worth..
anyways, great work with the series, some are indeed magazine worthy...
