Imo there is too much sharpening, especially in the 2nd image.
The highlights on stone appear to be slightly overblown too, both of these make the images very noisy to look at. (not meaning iso type noise)
The frame/crop appears odd too, they make me want to see the rest of the buildings, especially to the right of the 2nd shot.
Nice subject, surely the the water in such a climate has a good colour ? maybe try desaturating a bit, rather than making b/w.
