Thanks all
I'll admit now there is a reasonably high amount of post processing to make it so vivid, I upped the blacks to get a perfect silhouette, put some vignetting on and increased the saturation and vibrance to bring out the colours. Very pleased with the result though.
I took over 1000 shots in Moscow and Im not overly pleased with any of them, admitedly most of them were holiday snaps so I didnt expect much. I'll upload some later this week I expect, see what everyone thinks.
