Generate a super-realistic female portrait with a bit of “写实动漫” temperament, with the character standing on a pure black background.
Light: Use a **narrow beam spotlight** to only hit the center area of the face.
Requirements: The edge of the beam must be sharp and dramatic; the area outside the spotlight must quickly fall into deep black (strong attenuation shadow), almost blending into the black background; no soft light.
Hair: Long dark hair, with some strands falling on the face; the lower part of the hair gradually fades into shadow.
Posture: One hand is slightly raised to the lips, showing a shy and hesitant movement.
Eyes: Looking directly into the camera, with a mysterious temperament.
Clothing: Black long-sleeved knitted sweater; most details of the sweater and body should be engulfed in darkness, leaving only minimal outline information.
Overall tone: dark, emotional, dramatic, mysterious; contrast mainly concentrated on the illuminated facial area; almost invisible outside the spotlight.
