Thank you both. Geaux: in fact is cropped from a larger scene, but if I move the red bars on right, the left wall become heavier to see. As is, it is more or less divided in three thirds.
Joel: thanks. By the way, #5 is the fountain just in front of United Nations; #6 is made with an old manual Voigtländer Ultron 50/1.8. It is a nice lens, very sharp even wide open as here (the same as Zeiss Planar).
I really like #4 and #6. I actually really like how #4 is framed, but I feel like the framing is a bit off on #6. I don't know what feels off about it, maybe nothing because it's still my favorite shot out of the bunch.
