These photos look great. My concern when looking at the set you've shared here (there are obviously more) is that it places perhaps too much emphasis on the environment. The environment is cool, and you've captured that well here, but I feel like the couple gets lost in that environment and become somehow more anonymous because you're not really seeing their faces and expressions as much as you are the walls and textures of the building itself. The shots of the couple presented here have a kind of distant rather than warm and intimate tone even if they're beautifully shot.
