A full-body cinematic portrait of a deeply unsettling humanoid alien standing alone in a dark rocky ravine, centered in the frame and facing forward in a neutral upright pose with both arms hanging low at its sides. The creature is extremely tall and emaciated, with elongated limbs, narrow shoulders, a sunken torso, visible rib-like structures, taut sinewy anatomy, long forearms, oversized hands with long thin fingers, and long digitigrade-looking feet planted on wet black ground. Its skin is hairless, slick, pale gray-beige with brownish fleshy undertones, semi-organic and biomechanical in appearance, with glossy damp highlights, leathery textures, stretched membranes, tendons, grooves, and subtle vein-like striations. The neck and upper chest are fused into a disturbing organic structure, with tendril-like folds and open channels running from the clavicle area upward into the head. The head is broad and mushroom- or hammer-shaped with a ridged crown and flared side lobes, giving a nonhuman silhouette; the face should feel unreadable and alien rather than cute or familiar. Place the figure in a narrow canyon of dark eroded stone, with 2 large foreground rock masses framing the subject on the left and right, and a misty cliff wall receding behind it. Use cold desaturated lighting, soft fog, damp surfaces, shallow atmospheric haze, and a grim monochrome palette of charcoal, slate, ash gray, and muted flesh tones. The mood should be uncanny, realistic, oppressive, and biologically plausible, like a high-end sci-fi horror still. Ultra-detailed photorealism, sharp texture on the creature, subtle depth of field, dramatic natural backlight from above, no clothing, no tools, no background creatures, no gore, no text.
