I really like the humor seen in this Super shot. The fancy level of dress of the woman makes me think of a celebrity - pearls, gloves and fancy umbrella (I love umbrellas). I find it very amusing that an invisible woman would be annoyed/worried about her picture being taken. I get the feeling that we are the paparazzi taking pictures of the invisible woman and she is holding up her hand in the defensive 'push away/go away' stance to tell us to stop.
Very nice. I like the composition and generally the b&w idea. Also like the way you had the "spot light" on the background. What is a shame is that the detail of the white pearls against the white background gets lost. Still, really cool pic
