I think you got lovely shots of the bride/couple especially#12 & 13 and 20; you take interesting and unique photos (like the one of the tie!). I'd think about the framing of some, if that were my dress I'd want to see the whole thing rather than ceiling, but I think what you might have been seeing was the light hitting the ceiling which gives it some interest; I'd have thought about maybe a vertical shot? or some way to include the entire dress and the light above the window.
There are some where there's a lot of space above the heads but the subjects have no feet, or fingers are cropped/not in the frame, etc. Some of the B&W photos look gray more than black and white, but I like the outdoor shots at the end, those are pretty cool and I think them being backlit works.
