The first distraction has been noted, the plate between the faces. Also, the wall piece above the gentleman's shoulder does encourage the eye to venture there for no good reason, plus I think the gentleman's shirt is a bit bright, detracting from the couple's faces.
Personally, I really like the light to dark transition in the shot and gives it some chairoscuro effect.
Lastly, I would have liked to see the woman extend a few of her left hand digits. They look truncated as a whole.
Very nice setup and execution overall. Thanks for sharing.
