This has really bad perspective distortion which makes the subjects look really weird. The background is also affected due to camera level and using a wide angle lens which takes away from the subjects. I'm guessing the camera-to-subject distance was fairly close as this is what causes undesirable perspective distortion. For this sort of shot, you need to be at least 3 metres away from your subject and use a focal length of something greater than 50mm (equivalent to a full-frame camera).
Otherwise, it would be a nice couples snapshot, nothing special except for the memories. The lighting could be better, but fine with what you had to work with. A fill flash may give your subjects a bit more pop. Personally, I would have gotten rid of the sign, but I may not have gotten the pun if one was intended.
Better posing of the subjects will also help if you want some glamour (hand/arm position, angle of bodies, feet/leg position).
