Tidal citadel harbor concept

Paint a fantasy harbor city whose central citadel rises from a dark tidal rock. View it from a working quay with rope coils, timber crates, and a small repair shed in the foreground. Let a stepped stone causeway lead from the waterfront toward the citadel, remaining visibly usable by people. Combine pale plaster houses with weathered copper roofs and one tall beacon tower. Use low golden light from the right, cool water shadows, and light atmospheric haze to separate the city layers. Keep the scene inhabited through a few small workers rather than crowds. Avoid floating buildings, inconsistent scale, and unrelated futuristic spacecraft.
