I feel the subjects are sort of dwarfed by the trees. The trees are denser, more intricate, and so much visually larger, it's almost like they are the subject. It's a beautiful shot, I guess I'm just saying I think the story I get from it may not be the story you intend.
I like the emotion here. I think I would have cropped off the upper 1/4 where the tree open up a little. That would frame the middle better and bring more empassis on the couple
