Imbalance - lack of proportion or relation between corresponding things. Shots with strong points of interest on one side of an image and ‘emptiness’ in another area. Misproportioned.
I don't think I get this. But I'm giving it a go.
This is my second attempt. I posted my first earlier today and thanks to a helpful comment from Adrian, I've cropped the second shot and deleted the others. I know I'll be having a good look here to learn more about imbalance.
