I like the big version best. I thought it was a plane or a car - what is it really ? The big version is already a very close-up image and here you can at least have a guess what it is which you can't in the cropped version - at least I can't .... It's just three letters floating in the sky. In the big version there is context enough to have a guess about what it is. I like the green and blues together too. Gitte
