ภาพพอร์ตเทรตสยองขวัญใบหน้าแยกส่วนอสูร

Extreme close-up split-face horror portrait cropped tightly from [hairline to chin] against pure black negative space. The left half shows a [pale human face of a young woman with sharp dark eyes, a single crimson catchlight, and blunt bangs], making unsettling direct eye contact. The right half transforms into a [monstrous demon jaw with rows of jagged fangs filling forty percent of the frame, shadowy fractured skin opening into an abyss-like black void mouth]. Thin [glowing red thread-like cracks] spread along the transformation seam. Black and white high-contrast photography style with hyper-detailed skin texture, highlighted by dramatic single-source rim lighting catching the eye and teeth.
