The palette
Two reds, and keeping them apart is what makes this print specific: the red-brown sandstone of the ridge and the caves, and the brick red of the terraces below. Let the old core carry a fine dense weave with no grid to fall back on, and let the Meadows be frankly regular underneath it, so the two halves argue. Give the Trent a broad calm tone but keep it low in the frame; it borders the city, it does not run through it. Green comes in firm masses at the edges rather than scattered through.
