I took your photograph and applied a little more USM to show you what I meant with the previous message. I ended up applying USM with 0.3 radius and 260 level. It is of course possible to do a much more careful sharpening that will affect only the necessary parts.
This is one of my favorite views of Istanbul, view across the Golden Horn towards the old Pera. It superimposes the old, the Galata Tower, and the new, many modern apartment buildings. The dark sky, although looking ominous, works in this photograph. The seagull is a nice touch. I think you could apply a little more unsharp mask at a low radius, say 0.5. The edges are on the soft side.
I have a Coolpix 995 too, a very good camera. Although I bought a Canon D60 last summer, I still kept the Nikon CP 995. You may want to try configuring the camera with no sharpening and normal or low saturation. They are best applied in Photoshop.
