I think the exposures and stylings are all spot-on.
However - and this is just opinion - I think the long strands of grass and the seed heads are distracting and incongruent (what's she doing in a marsh?) in the first image, and that the center horizonal line makes the image less interesting. Also, she doesn't seem to really be interacting with the sax in the first one, simply holding it. I mean, like a prop, not like a musicians usually caress their instruments.
The sign and the composition in the third are really good, but the model's expression kills it for me. YOU caught her between mouthpiece in place and a normal expression. It looks like she's just about to say something to you. (This could be a personal dislike, because I so frequently would catch my wife just as she opened her mouth, usually to say, "Take the stupid picture already.")
On the other hand, I really like the second image. I think it's a good angle - she echos the shape of the clocktower, unusual but not confusing perspective, dynamic. I don't find the lighted clockface distracting. She looks like she's enjoying herself, yet her face is not so contorted that you can't tell that she's a beautiful young woman. So, for what it's worth (nothing, actually), IMO, the second image is the hands-down winner.
Thanks for sharing.
