Two astronauts traverse the barren landscape of an alien planet, one gripping a sleek visualization device that casts faint holographic projections around them. Nearby, a mysterious alien structure looms, its architecture both ancient and otherworldly. A series of distinct footprints mark a path leading towards the enigmatic building. The scene is depicted in a concept art style, a digital painting infused with futuristic realism. The flat landscape and simple details are rendered in muted, low-saturation tones, echoing the nostalgic, surreal style of Enki Bilal.
