Townscape is roughly synonymous with Cityscape, though it of course implies the same difference in urban size and density and even modernity implicit in the difference between the words city and town.
In urban design the terms refer to the configuration of built forms and interstitial space.
In the visual arts a Cityscape is an artistic representation, such as a painting, drawing, print or photograph, of the physical aspects of a city or urban area.
