To me, all the pictures in this series that you have posted, suffer from one thing only...the light. It appears that you took these when the sun was at it worst. I know that these things are often out of our control, but it has left these photographs with a pretty "harsh" look.
I think that, apart from that, they are all "iconic" for you. What I mean by that is: those are iconic locations, photographed many times by many great photographers, but, I would rather hang my own picture of an iconic location than buy and hang anyone else's. I hope that makes sense?
