Due to the backlighting causing the Silloutte (i can't spell), it makes this photo quite dark. I like the idea of the framing between the two trees, and the branches above. The foreground though with the seats adds nothing except dark areas. If you had of cropped the seasts out, it would of then had the dark silloutte at the bottom, the couple then in the foreground more, and removed those seats out. The photo then would not have seems as dark as well. Then the photo I think would have scored much better.
I like the idea you had. With the changed crop (and ideally a blue sky) this could then have been stunning.....
