Mars Fortress: Epic Concept Art on the Red Planet

An imposing fortress carved into a Martian cliffside, basalt towers and glass observation domes rise from red ochre rock. Wind sculpted dunes and layered canyon walls frame the fortress, with a network of solar sails and landing platforms clinging to the cliff face. A dry riverbed of iron dust winds toward a valley. Inside corridors glow cool blue light while Martian sunlight casts warm orange highlights. Cinematic concept art style with painterly textures, ultra detail, wide angle perspective, moody atmospheric haze, subtle sci fi tech details like airlocks antennas and modular habitats. The scene conveys ancient fortitude meeting frontier science on the red planet, Olympus Mons faint on the horizon. Palette combines deep reds rust and ochre with cyan blue accents. Golden hour lighting with long dramatic shadows.
