Some nice captures. Although I have to say that 7 doesn't look very flattering to them. The posing and angle used makes her look bigger than she seems to be, and makes him look shorter and squatter than he seems to be.
I think 11 would be stronger if he were looking at her and his right hand had some contact with her.
I like 5 the most probably.
I understand the night scenes are going for a more moody, serious look, but I'd have liked to see some more playful interaction, some of them she just seems pissed off at him or vice versa like they had an argument. I like the compositions and the lighting, just not their expressions (especially relative to the first location).
Just my 2 cents
