Consider the previous version a draft, a collection of images to be potentially used. I wanted a mix of color and B&W, some close-ups, some body shots, some posey some candid. The selected photos have simple backgrounds - I have other photos of babies with toys, or on quilts - for an ad, I opted to avoid eye distraction. Limited color palette.
Had to crop images in rectangles so that they fit nicely with each other. Staggered the pics so that each photo created its own border - e.g. had I put 2 pics with green grass in the background, the individual pic outline would be harder to define, and thus less tidy looking. Put a generous white mat around the whole thing, to give it a framed-picture-like presence.
