The palette
Water makes the entire composition here: it enters at the top, runs down on the diagonal and opens at the bottom. Take it frank and deep, it is what has to carry that diagonal, and do not fear its dominance, it is the subject. The built fabric opposite should stay a single pale value on both sides of the strait: their likeness is what makes the cut interesting, and colouring the two shores differently would explain what the print already says. The green of the northern forests, though, deserves to be frank: it is the one breath on the sheet.
