The sky in the background is very distracting.
The layout of the photos doesn’t add any feeling of the image
The ‘cutting out’ of the images with the wavy bottom is very distracting
The facial expressions are not different enough to warrant 5 images in 1.
Might be worth just going with 3 photos and leave them with their natural background and just lay them horizontally or vertically alongside each other with a tidy border!
