Nice classic shot of railings/bridge parapet. Probably just needs something to break the rythm, a bird or coke can set 2/3 of the wy down.
I think a 6 is appropriate
Nice rythmic shot, but it's lacking something else interesting; also there is a lot "junk" in the background. Also, I would probably flip the shot, so that the perspective would go left-to-right.
