It's a perfect 10 from me, great picture and nice processing. Hey, I'll be on that very bridge on Saturday, I'm travelling down from Nottingham with local UNISON to join "The people's march for the NHS"!
simple and beautiful
Full View is excellent
9+...Great capture for a single file. My crop suggestion is only to avoid the people walking down on the right...
i like it. I don't mean to be picky but it seems there is a halo around some of Big Ben.
In my opinion: subject - 10, composition - 8, process - 9. Overall - 9.
