the first one is really cool!! I love it! I love the angle and tones. and of course her expression! I'm not sure about the second one because of a shadow on her left eye (not very visible but it is there ) but the first one just rulez here
I agree with everyone else so far, not really feeling the 2nd because when I first look I am automatically drawn to the chin in the top of the picture...... the 3rd I think that the guy distracts from her, a portrait is supposed to have the subject as the main object, but I see the guy first. The first is great. I love it.
