*clicks knuckles*
Right, here we go! to start with, I second what Kenny has said, the flash is far to harsh and the shadows cast are a distraction along with the tilt.
The poses look a little awkward, the woman's nose should be in view (its generally smaller, and better looking then a males), her right hand looks weird/broken, and because the bed linen is white its adding weight on to her (helped by the pose).
And finally, be mindful of objects in the background like an ugly telephone
To the suggestions for next time bearing in mind that everything I say I was not there at the time, do not know the space/lighting scenarios that where there or how cooperative the couple where so everything could be relevant or irrelevant;
Try getting the bride to lift her body up off the bed by pushing on her arms, this should break up the mass a bit, nose to the front, get her to break her fingers (figuritivly speaking have the fingers separated rather then a mass like she was playing a piano).
Move objects out of view where possible,
If your going to use flash bounce it, if you are going for the spot light effect make it as narrow a beem as possible in the instance like this only lighting up the faces in the shot, ORRR, balance the flash with ambient by switching on all the lights in the bedroom (manual and metering plus bounce flash I find the best way).
if none of these where possible at the time forget what I just said
