I noticed you did a wipe from the wall of photos to the one image there at the end. Have you thought of doing that several times? Have it transition back to the wall of random photos between each picture transition. It’d be a different look. You could mix up the transitions, and blow through about 20 or so pictures from that set.
My experience on family photos, is despite their best intentions and insistence on including EVERY photo they give you, including similar looking photos is a bad idea. It’s the slideshow effect. Would you sit through a slideshow: “Here’s Marge and Me at the Grand Canyon. Now here’s us at the grand canyon wearing silly hats. Now we’re wearing silly hats and shirts.”
It gets old. My sister dumped 100+ photos to convert to a slide show for my mom’s 50th, and I had to toss half the pictures. There were a good 40 pictures that were retakes, or pictures taken at the same time with the dog, then the dog with a hat. I’d drop the dog w/ hat picture and move on. It made for more work for my sister (since she had to go find more unique photos), but it made the presentation a whole lot more bearable for the party guests.
