I'm glad the bride likes them! I'll echo David and hope you post at least a few from the actual wedding.
However, I agree with you; the "something" is missing. The pictures feel stiff to me, and too posed. There are too many "and here we are standing there,
and there, and there" shots, and not enough movement or sense of context or simple spontaneity (conveyed) for that matter.
The future bride is especially hyper-aware of you. Even though there is a hint of playfulness, it's of the type where they know when they are photographed, and they only play when the camera is on them. This set of photos comes off as a sort of model shoot, because they are looking at the camera frequently and when they aren't looking at the camera--they are acting, rather than just living. I dislike the mock-excitement shots. (108, 110. 957 to some extent.)
The wedding should be a bit better in regards to the comments I've made, because I'd hope that they'd be a bit more preoccupied with getting married than being photographed. If you have to---I'd figure out something to tell them to get them to stop looking at you.
There should be some posed shots (standard mugshot-type), of course, but there should also be photos where they don't know the picture is being taken.
I don't have much else, but I'd try for a few more establishing/context snaps, and a bit more creativity in angles. Oh, and especially during the wedding, make sure that you get the bride in frames without the groom, and vice versa. Aside from the two hands in your gallery, where where your closeups?
