In my opinion there are some good things and some bad things about the processing. I don't think the skin looks overly smoothed (excluding the blown areas, of course). You can still see her freckles and laugh lines. One thing to be mindful of is what "imperfections" you remove. I'm specifically referring to the two spots on her left cheek. In general I don't mind removing transients - pimples which wouldn't normally be there, for example - but I don't remove permanent marks (moles, birthmarks, etc). Such things are visible every time the person looks in the mirror (or in this case, since we're really talking about pictures of the MoH for the bride to see, every time the bride has seen her) and are part of that person's identity and personal image. Just imagine how off a picture of Cindy Crawford would look without her famous mole. What you can do is minimize them if you see fit, by using the clone tool at <<100% as Trevor suggested for the blown areas. I also like your whitening of her teeth - very clean, but not so white as to appear freakishly unnatural. If this were a fashion shot I'd say you nailed it - here I might dial the cleanliness back just a tad. Again, she knows her teeth aren't nearly that white (unless the original has white balance issues and the teeth are whiter than they appear there), but also because you don't want to upstage the bride - make sure her teeth are just barely not quite as white as you make the bride's and the bride will on some level appreciate it.
I agree with Trevor that the background is too black. You've lost all distinction between the background and her hair (and her dress strap, for that matter). It also looks to me like there was some feathering of your mask - there is a gradual shading which follows the contours of the black which removes all sharpness between elements (her skin to the background, and even her dress strap to her shoulder).
Overall I think you're on the right track. Rein in what you did just a touch and I think you'll have a solid image.
