I soon realised I had made a huge mistake, I had made all of my images exactly the same size with almost no room for cropping or changing. This meant that I could not really have any veriaty in terms of pannel shapes, for example longer ones or shorter ones in different positions like the first image.

There where only really two things I could think to do that wernt just one pannel in each corner and that was by having one image as a background and using the others on the top, and secondly by cropping the images as much as I could to make more interesting shapes.
