Lovely romantic image, you have retained great detail and character in your image. The poster of the seat makes the image a little more interesting but i’m not sure why. Maybe its the image within an image that catches the eye. Nice piece of work.
It might be worth looking at it without the pavement in the foreground-
the pattern of the steps is probably enough on its own,
and would maybe concentrate atention to the top of the picture-
compositionally, I find myself a little distracted by the strip on the bottom-
