Nice photos. If that's all you wanted to hear.. /end post.
If not, keep reading.
To be quite honest, the shots do nothing for me. This isn't a direct attack, but rather a general opinion. Too many wedding photos look the same. I know it's the clients who get to choose, but it bothers me.
Technically, although I'd need to see larger versions, I find the first one to be a bit soft (might be your lens). The 3rd and 4th ones are very underexposed (I guess you didn't use flash?) and the second one doesn't pop at all (again, no flash it seems). I'd say you should get yourself a flash. In the second photo, I'm far more interested in the background than the bride.
Conceptually, I like the first and fourth ones. By that, I mean they're the most original of the four.
Oh and the first one has some harsh bokeh.
Check out Flickr for some motivation.

This guy is my idol in terms of wedding photography. Check him out.
I write all this not to bring you down. I really think you have a lot of potential (granted I only saw 4 photos). Keep it up!
Edit: I proceeded to check out your site. A lot of great shots in there (from past weddings). For some reason though, these 4 don't stand out as much.
