You did a good work with the camera. You will definently grow more in youre skills if you follow the advices here.
None of the pictures are over the snap shot level, but they are all good enough to be kept as a great pictures from a great day. If you are planing to take the wedding shots for youre family members next year, I would recomend you to ask them to at least take some studio shots from a pro. That will give you less pressure on the day.
