Hi David
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?
