A lone astronaut crosses red Mars as the camera reveals an alien structure on the horizon

Prompt

A lone astronaut walks slowly across a barren red Mars landscape. Their reflective visor shows the setting sun. Dust swirls around their boots with each heavy step. The camera tracks alongside at medium distance, then slowly tilts up to reveal a massive alien structure on the horizon. Cinematic sci-fi, blue-orange color grading, volumetric haze, epic scale, Hans Zimmer-inspired tension.
