|Hi Stanley, welcome to the Critique Zone!
It's a great shot, no doubt about it. Really nice structural framing from the bridge silhouette and a well posed relaxed model (it matters!).
Technically: Nothing to say - 30 seconds seems like a slightly unnecessarily long expsoure (and would have hit the noise levels hard), but the final result really works.
PP: There are a couple of comments on noise (including yours) but it's not really a problem for me. If it really bothers you then as I said, a shorter exposure at maybe f8 would maybe help.
Artistically: I really can't add anything about the shot - I would not have done this so well, it's a great vision. THe border bothers me though. The big letterbox is ok, but the bright white strips on the dark picture really grab the eye away from what I want to be looking at - your photo.
Overall, great take and congrats on the top ten finish.
