You can really make yourself crazy with this design even though it's meant to be a simple one. I worked on one at a charity sewing day. I was given a random number of animal squares. I tend to prefer symmetry. I almost went crazy rearranging the animals 'til I finally added four identical squares to use at each corner and eliminated a few animals.
Keep it simple, get it done! I like the first one but can see how the second could work with the right fabric.
