Hello fellow Canuck!
Great shots. Excellent model.
1) There are two lines on her right shoulder.
As I have read on previous posts, move her away from the fence (background) so that it blurs through some shortened depth of field.
I like the light and shadow play.
2) maybe a crop just below the wrapping paper bra (very cool bra, btw!).
Her hands could be placed with the middle to ends of her fingers resting on the metal railing instead of her wrists - unless you were looking for a bondage theme - then I would have tried to use the same paper as her bra to tie her to the railing.
3) is very cool... one problem and I have no idea how to fix it, is that her noes is smack dab in the middle of the link and with the lighting, it seems rather pronounced.
And for a different look you might want to have a shot where she is in the same body position, but one) have her eyes look down at the camera and/or two) have her head and eyes looking down at the camera. She has a strong look to her and you could try and work with it some more...
Hope that this is helpful.
