For the pages that have images on top of images.....I would desaturate the background image some, so that the image on top POP. I'm assuming you want the top images to draw the most focus, or they wouldn't be on top of another image.

Also, for these same pages, I would use a light stroke (border) around the top images, to also help them stand out from the background image (like you did for the first page with their names. Another small thing.....I would change either the font of their names or the font on the date.....It usually looks better with a contrasting font in that situation. Personally, I would use a block font for the date....but that's just my opinion! I agree with the previous poster was well about the first half being very crowded and the last half using more negative space. I would break it up.....you could probably drop some of the many images in the getting ready sequence or maybe lose some of the background images.....
Hope this helps!!
