What aren't you happy about mate?
If I had to critique it I would say there are too many distractions in the photo to make the couple really standout. Having them against those upright railings on the right could have made a nice high contrast style shot.
Your right, there's an awful lot going on. I think that might be it, as it was supposed to place emphasis upon the "couple" (Me and the Mrs lol) and the photo is very busy.
I think I have a few from the railing. Might process a few more this evening.
