Ultra realistic 4K horror portrait, strange young boy, full body shot, abandoned house. Child in sharp focus, strongly blurred background. Uncanny face: pale cold skin, very dark tired eyes, one eye slightly higher, unnaturally still expression, narrow crooked nose, thin lips, slightly too wide mouth, small uneven teeth, long thin neck, sharp jawline, messy black hair, protruding ears, disturbing asymmetrical face. Body slim, stiff, unnatural: arms hanging too straight, long tense fingers, slightly hunched shoulders, feet turned inward. Wearing old oversized knitted sweater, dark shorts, dirty socks, worn shoes - clothes from another era. Background: dark corridor, cracked walls, half open old door, faint cold light, floating dust particles. Vintage psychological horror atmosphere, shallow depth of field, cinematic lighting, 85mm lens, realistic skin pores, highly detailed fabric, unsettling mood.
