Alien Mothership Dusk

Create an award-worthy Hollywood science-fiction movie still as a native exact 4:5 vertical full-bleed gallery-card composition, adapted from a cinematic widescreen idea without adding borders or letterboxing. Digital cinematography, aerial view, medium focal length, medium shot scale, medium depth of field, planar lighting, medium contrast, dramatic side-backlight with direct hard illumination. Subject: a gigantic, complex alien spacecraft hovering menacingly over a futuristic metropolis at dusk. Use cinematic composition, ultra-fine detail, photoreal realism, subtle film grain, anamorphic lens flares, volumetric lighting, cool cyan-and-orange color grading, epic scale and a feeling of approaching doom. Keep the alien ship, city skyline, strongest light shafts and atmospheric depth comfortably inside the central safe area while filling the entire 4:5 frame. Avoid black bars, side margins, poster border, over-dense clutter, copied movie franchise designs, real logos, watermark, giant text, cropped spacecraft or low-resolution blur.
