Dramatic. I feel the forced vignetting adds to the drama. I don't know if this was intentional, but the cloud shapes towards the edge of the image look painterly, almost geometric, not photographic. To me this adds a tension to the image; adding to the drama.
Great dramatic b/w image. My only critique... I would have cropped a bit tighter, some on left and more on right, to make the cityscape larger in the background. Not a huge crop and still keep it off-center, but found myself wanting to see more of the city on the shoreline! FYI, I have the 21 Biogon for my M9. Fantastic optic!
