Great shot man! Were you using an ND filter or a CPL or anything on this shot?
Beautiful picture! You captured it at a perfect moment and balanced artificial lights with the natural background.
Have you tried sharpening for output after rescaling for Nikonites? Would be nice to see more details on the buildings. My feeling is that the rescaled version might have lost some of that.
I'm with @ditonics on this one, I think the HDR version looks amazing. The extra color pop really sets it off for me.
Is your HDR version in-camera HDR or 3 manual exposures post-processed in HDR?
