The palette
The sea takes half the sheet and there is no other mass: everything turns on it. A deep water ink gives a blunt print in which the town is only a pale border; a paler one gives you the bay and lets the town breathe. Both work, but they do not tell the same story. Then keep a slightly denser value for the built fabric, or the upper town will not stand apart from the rest, and the upper town is the subject. The pale zone in the south will stay pale whatever you do: it is not water.
