Sorry I've been MIA again, just catching up on my sleep now that my back is feeling better :-)
About the shot:
Standard +2/0/-2 HDR
Topaz De-noise to make it smoothy
Topaz Adjust to tweak it.
Some dodging on the buildings
Fx Foundry scripts for local contrast enhance, smart sharpen and LOMO effect (vignetting)
Cloned out some smudges and a few ducks that just looked like blobs :-)
