Of this selection, I gotta say it isn't your best e-session I don't like the last one because the couple seems like an afterthought to the photo, while the main subject is some metallic edges. #2 is the best of the series in my book. I checked out the blog post and there are stronger images there. Generally, I find your e-session work among the best.
Its really interesting how some of the bolder images really polarize people on this forum. I prefer the third one too. I agree that the couple are not so dominant but it doesnt mean the shot has failed.
I really fall for the whole juxtaposition of romance and a kind of grotty, industrial setting. For me shot pushes my buttons on a few levels.
