Generate a 3D horror character of a terrifying little boy in a T-pose. His face is grotesque and unsettling — hollow black eyes, cracked pale skin, unnaturally wide grin showing sharp teeth. His arms are twice as long as normal, ending in thin bony fingers. He wears a torn, old-fashioned school uniform with no shoes, feet bruised and dirty. Realistic, cinematic horror style, eerie atmosphere, high detail textures, optimized for rigging and animation.
