6 - Like this. Criticism; in my opinion, a tighter zoom/crop (if possible), aiming for the 'smoke/steam clouds' to really dominate this shot, would have made it even better in my opinion. The colors are also nice, but would like to see them a bit more vivid, perhaps it is the lights that are competing with them too much, not sure.
I love the movement of the steam/smoke. The blur of the lights on the water helps add to the shot. I'd do a bit of saturation work to really up the sky and wate tonesr.
