The last one has potential, but there's a basic problem of scales. The figures at the bottom of the frame want to be interesting, but I find them to be just too small and muddled to grab me, and yet without the entire building in frame it's a completely different image. It's possible that in a large format and placed quite high to bring the bottom edge into the eyeline it would be very very successful.
Printing large and mounting high is a very good idea.
