Patience grasshopper, it often takes more than 45 minutes to get answers out of people!
Quick comments...your closeups (1,3,5) tend to have odd framing, with the eye-line of the subject very close or dead on the centre line of the photo. Not typical if that's what you're going for, but rule of thirds would 'standardize' them and get rid of the extra space above the subject's head.
The wide portrait (2) is a good idea but the pose is a little forced...you can tell she's not relaxed because she has a white-knuckle death grip on the railing
4 is your best shot, nice lighting, background/bokeh, I like the vignette look in the processing. Although the subject is a little central for my liking I think the shot works because of the leading angle of the as it transitions from foreground to background.
