Thanks again oof. I'm still understanding the workings of Silver Efex. I've found if one pushes selective area adjustments too extreme, the image begins to degrade quickly, especially high-contrast edges.
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!
