I don't really care for the unevenness of the blur. I think you had a good idea, but it may have been better with no blur on the left and a progression to the right. The blur make s the picture offset and my eye is drawn to the blur of the far right 1/3 of the photo rather than to the subject.
highlights gone in the front of the dress. i would have cropped a little tighter (having photographed around 500 weddings...) since the bride's maid is adjusting her dress and not real flattering to her. last bride's maid on right is way too out of focus. curious, did you (over)use a 'lens baby'? i can go with a 5 but no higher.
did you shoot this with a lensbaby, or just apply selective blur? it's an interesting take on a common subject...certainly makes for a more compelling wedding shot.
