C&C per req:
1. Hmmmm, a nice attempt, but I don't think it quite makes it for a couple of reasons. First, her expression says to me, "What the heck did I step in?" and not "I'm excited to be getting married!" and from a compositional aspect, it's usually better to have the empty space in front rather than behind the subject. Also stay alert for distractions such as the plant image right.
2. Slightly over-exposed (wedding dresses can be miserable, I suggest using your EC and going 1/3 stop either side for white outdoors on a bright day) and not fond of the angle, but that's a personal preference.
3. Nice, but could use a little brightening and saturation boost.
4. Nice pose, but I think the WB is a little off.
Overall, nice work for a first wedding.
Just my $00.02 worth - your milage may vary.
