I don't and won't shoot weddings so this is just my personal thoughts.
#1 - very pretty shot, a touch overexposed on the center of the dress and it is showing a slight blue cast in the whites but it is not so distracting to make me dislike the shot.
#2 Again a nice shot, very classic and the blown out window is so in with art directors now. A perfect example of artistically breaking the technical rules. Again there is a bit of over exposure in the center of the dress but much less then in #1 and the white balance looks much better here too.
#3 Sorry the crop just does not work for me. It is too tight and too much of the story is lost as a result. The tight crop forces me to look too long to find the story line and by the time I do I am bored and more on. There is just not enough emotion, tone or contrast to grab my attention.
#4 Is either brilliant post production or brilliant luck to have such a dramatic sky at the end of a wedding shoot. I kind of wish the groom was in the shot too, maybe hunkered down in front of the car hiding. I would not make the image brighter, I think it would detract from the mood.
#2 is my fav of the bunch but #4 is a great bit of editorial bridal fashion
