Ideally the 33 buildings poster can add and replace what's currently on there with newer buildings both tall or not. I guess it depends when the current batch runs out and when time to print new ones.
And plus that Willis Tower doesn't appear to have those glass boxes on the side it's on.
I really wanna get it! I actually have one of your really old posters from like 6 years ago. I got it at a flea market for five bucks. I'll post a pic later
I would have to say that the star one looks kind of unsophisticated, particularly in contrast to the intricacies of the details gone into the diagram.
How about a translucent montage of stretched diagrams as a background which would also act as an excuse to sneak in more diagrams on it even if they're not supertalls.
I loved the impressive details of the diagrams showed more than the posters itself, however I see the Star look fits more to a 50ies 'bar' club decoration, comparing the clouds one to a younger room dormitory. Both are valid contrasts for different Environment, my opinion.
