Watercolor painting with Pop Art verve, sepia-toned washes bleeding into halftone dots and thick comic outlines; firelit amber-gold glow. At the golden-ratio sweet spot, a tall scarlet-red buoy with a brass bell bobs, ringing as tide rises. Around it, small brass crabs trade shiny pebbles through a tidepool of tarnished gears and glass marbles; warm shadows dance, nostalgic paper texture.
