Prompt
A vast abandoned tidal observatory stretches horizontally across an alien salt marsh at night, its low brutalist platforms connected by narrow elevated walkways. A lone tiny maintenance rover with one amber lamp crosses the foreground causeway toward a squat circular listening dish on the right. Far behind the platforms, an immense burnt-vermilion planet hangs low above the horizon, its lower half swallowed by dense blue-green atmospheric haze. Compose a 16:9 wide frame with the walkway cutting diagonally from lower left toward the right-hand observatory and the planetary disk offset toward the upper left.
Render this as a dark, tactile retro science-fiction illustration reproduced on aged matte paper: fine coarse film grain, subtle ink abrasion, scratchy etched architectural lines, crushed charcoal-green shadows and restrained teal edge highlights. The orange planetary surface is flat luminous pigment with ragged mottled texture rather than glossy volumetric light. Broad quiet dark areas contrast with intricate low silhouettes and rippling shallow water; reflections break naturally around salt ridges. Maintain a sparse, ominous editorial print atmosphere, a clear horizontal silhouette and purposeful small-scale mechanical detail.
