I've attached four rudimentary designs, one for each main balance category. I decided to set myself the task of doing all the designs with one basic image - hope that's ok. I'd like to have done more but ran out of time - I spent a disproportionate amount of time looking through books to find the examples but, boy, was it fun! I'm a bookaholic so have PLENTY of images to choose from.
I've also attached four examples of images, one for each type of balance. I found it difficult to keep to 4 images - so didn't :-). 1.9 is there because it made me smile.
