Silhouette solitaire dans une mégastructure en ruine

Widescreen cinematic science-fiction concept art in [cold monochrome gray and black] tones, depicting [bleak post-apocalyptic solitude]. The setting is the colossal interior wreckage of [a crashed alien megastructure], viewed from a low ground-level perspective under an enormous dark ceiling slab that dominates the upper two-thirds of the frame. In the distance, standing slightly right of center, is [an unnamed dark-haired woman], tiny against the monumental architecture, with long black hair, pale skin, and a flowing dark-and-white layered outfit. She is surrounded by shattered metal plates, collapsed floor debris, hanging cables, jagged beams, and broken hull fragments, with three massive curved structural ribs receding into a bright misty opening behind her. Lighting is [harsh white backlight through fog], flooding from the left and rear to create a bright foggy exterior glow and deep silhouettes in the foreground. Matte-painting realism, high detail, sharp angular industrial geometry, subtle dust haze, no text, no watermarks.
