First, welcome!!!
I agree with Marko, besides the bride, the most important thing in the wedding is the dress (probably more than the groom).
There is WAY too much background and her position in the frame is not working. If you would just crop out the ridge of bricks on the right side of the frame, it would be a lot better, more uniformity.
Another thing I see is her expression. She looks uncomfortable. This is supposed to be her happiest day of her life, make sure you capture it.
