I really like the unedited sunrise shot actually, I'd maybe tweak the contrast a bit and then it would be spot on for me with just edge detail of the buildings coming through.

Moscow's financial district makes Canary Wharf look uninspiring! Some nice shots there especially considering they were holiday snaps as you put it, I love the reservoir and the colourful church shot.

Looks fantastic as a Desktop background
