Very nice, good exposure and use of selective focus to highlight the main subjects. I would suggest a closer crop however. Perhaps from second panel division on the LH side (which would also eliminate the somewhat distracting angled bit) to just to the left of the RH most guard-rail support and place the main subjects a little more off-centre.
the soft,tender lighting on the couple and all around....and the lovely pastel shades of white and grey are the highlights of this quite,attractive,sexy,romantic pic i just cant help but comment on the mans pretty long fingers!!!maybe he is a musician? maybe he is pretty good with his hands? only the woman can answer that.....!!! this looks like a candid shot to me,so getting the right composition is little tough.
Nice. I liked it. Agree with cropping comment above. Also, what on earth is the white object on his jeans? I would be tempted to clone that out.
