I love the cake photo its got all the detail you want with a great DOF... you should try selling it or work something out with the bakery that made the cake.
The other photos are stunning as well. You are going to give the real photographer a run for there money.
I really think you caught some great expressions in there, and I love the fact that you grabbed some of the sillier ones as well. You seem to have a great eye for capturing emotion!
No you have beutiful pictures my only thing is on some of the shots it seems that you cropped a little close... I think the photos with her dress running off the bottom edges (4,5,6) would stand a little stronger if they had the whole dress or cropped closer to capture greater details. You do have great photos Im just being nit picky and maybe its just me
