I have to agree, I think it might be a better idea to leave the photos out of the picture and stage it with just the rings, some flowers, and some lace.
The photos will come in much better if you scan them on a flatbed, adjust color individually, and place them in MS Publisher, or in Photoshop. That wil also allow you to crop them, tweak the positions of the individual photos electronicaly, and feather the edges of the images. The final effect will be more like a collage of images, instead of just a snapshot of some snapshots.
ETA: The smaller bad is geting a little lost the way you have it positioned - it's almost edge-on to the camera, which hides a lot of the ring's structure. You might want to move it to the front right instead of the back left. It's small enough that it won't cover up much of the larger band.
