The palette
Two sandstones share this city, the red of the eastern and southern tenements and the blond of the western terraces, and giving them two distinct ochres rather than one brown is what will make the print look like Glasgow rather than any northern city. Keep the Clyde a dark ribbon. Glasgow Green and the Necropolis want opposite greens, one flat and open, the other dense and vertical. If you colour the motorway at all, let it cut against everything else: it is a scar, not scenery.
