I'll give you my very quick opinions - please read everything as constructive and imagine smileys on the end of each line.
1-2: I don't like the overlaid images, just go with the spread. Put the little images on the first half-page if you like, I don't really see how they tell muhc of a story.
3-4: dislike midnight sepia and mixing B&W and color on a page. B&W image will be chopped in half right? You could lose a lof it in the gutter. I like symmetry in page, so i'd try for the two large shots to be landscape (or portrait). Can you put a few more litle shots in?
5-6: not bad layout, again mix of color & b&w. I often go all B&W for prep images.
7-8: I'd remove the diagonal layout, go vertical.
9-10: I find the U shape of the brides head distracting - I like to see heads around level and the faces about the same size in this type of page.
11-12: Earrings image is weak, nice photo of people is too small. 2 page spread for that nice B&W one? Or make it span the pages and take up 70% of the width and move the small ones to the side?
13-14: Go for symmetry. Make the left side look like the right.
15-16: Simple, elegant. Best page yet.
17-18: could the car shot be a 16:9 ratio?
19-20: you'll lose the bride and Dad in the page gutter. Also funny boxes at bottom. How about two larger portrait images, one on each page, and move/resize the smaller images if necessary?
21: Is ok layout wise, try a plain white background and a black stroke around the images
23: Nice layout, B&W conversions need work. Again midnight sepia I don't like.
25: Group pic bigger? Span the two pages if you can make it work? Also in future get up high and put them in a more round group, that means less width so faces are bigger on the page.
27: Make image on right larger - align top with the top of the images on the left, ditto for the bottom.
29: Smaller image on top, larger at bottom? Bride pic on rt larger.
31: Move bottom right pic so it's right aligned with the wide pic.
33: larger image at top of left page? One sepia mixed with B&W I don't like. Vertical alignment of rt page to center.
35: Color/B&W mix - all b&w instead? The colors are boring in that location I think, distracting even.
37: See the redesign i'll upload in a minute
39: cramped on right. Consider removing landscape and one other image. If you have a single side (ie half spread) you can use move the right hand side to that and spread the rest of the images out more nicely. Not sure I like the very bold white line for the last image.
Hope that helps
