Focus is nice and sharp, I would have liked to have seen the depth of field more shallow, so as to isolate the groom and the father inlaw from the background. The chair rail on the wall off horizontal, and whatever the object is that on the table at left, distract a bit.
The picture could have been a little lighter, to my taste. There is some room for brightness, without losing the detail in the whites.
The cap tells us that the person standing is the groom, but I have to agree with some of the others, I would have liked to see his face and what he is doing to create the reaction observed.
I don't think it is necessary to see the eyes of the father in-law. If you are laughing so hard your eyes are closed, that tells a story also.
Nice phtograph, it makes me smile just looking at it.
