Joel, like Oleg, I can't like this shot, though I would like too.
There are several things, such as overall color balance, that effect my response to the shot, but I think I can be specific about what's really not working for me- it' the background itself.
The Christmas Tree is simply overpowering your subjects. That tree was decorated to be something to be appreciated on it's own. It's a center piece and the Bride and Groom can't compete successfully with it.
You included all of the tree in your composition, which, because of it's size, is stripping your couple's kiss of a lot of emotional energy and there is also the long apparent distance between the viewer at the camera position and the couple, which also reduces the emotional content. Since you haven't chosen to make the couple the important element of the composition, I'm not going to get a feeling for this couple.
If you crop in to pick up the intimacy and so the viewer can make a more personal connection with the couple, the background becomes very busy and distracting. The shot is better, but I don't think it's a strong picture.
Finally, a Christmas Tree is highly symbolic and brings with it a lot of associations, both personal and cultural, that don't have anything to do with a Wedding. Weddings, the idea of them, what they symbolize, again, have both personal and cultural associations that become part of the viewers experience. Trying to bring both sets of associations into one coherent experience oif the shot isn't very satisfying. You can try an experiment that may give a sense of what I'm saying. In you imagination, keep everything in the image just as it is, except change how the Bride is dressed. Put her in anything from jeans to evening gown and the shot will, more or less, work.
Anyway, my two cents is the background isn't working for the shot.
