Oh, thank you Alain! Some good ideas to think about!
I ended up with a new version that took up some of your hints, without being too strict. (It's a matter of taste, for some reason I do not like if everything is _too_ aligned.)
Also converted in B/W and changed the aspect ratio.
Still not sure whether it's a good picture, somehow I think there's still something missing (from the side of / as a subject), but it was a nice practice.
Thanks again to all!
