Kind of comic expression of the face. Asume its difficult to get the right exposure for such a strange and variable lightning but you seem to have got it ok.
The shadows are a nice touch - As opposed to a lot of the pictures with someone looking outside the frame and a only a title to relate with the challenge, this picture speaks for itself. I might suggest a wider aperture to blur the background if possible, but otherwise I think this is a pretty good shot.
Wonderful. The staging of the shot is fantastic, and I love the obvious use of venitian blinds here. The expresion on the model's face is priceless! 9.
