Hyper-realistic style female character portrait

Generate a hyperrealistic realistic-anime portrait of a female character 
standing in a completely black background.
Lighting: use a **narrow beam spotlight** focused only on the center of the face. 
The edges of the light must be sharp and dramatic. 
All areas outside the spotlight should fall quickly into deep darkness 
(high falloff shadow), almost blending into the black background. 
Not soft lighting.
Hair: long dark hair with some strands falling over the face. The lower parts of the hair should fade into the shadows.
Pose: one hand raised gently to the lips in a shy, hesitant gesture. 
Eyes looking directly at the camera with a mysterious mood.
Clothing: black long-sleeve knit sweater; 
the sweater and body should mostly disappear into the darkness with minimal detail.
Overall tone: dark, moody, dramatic, mysterious. 
High-contrast only in the lit portion of the face. 
Everything outside the spotlight should be nearly invisible.

站在纯黑色的背景下。
照明：使用**窄光束聚光灯**只聚焦在脸部中心。
光线的边缘必须清晰锐利，极具戏剧性。
聚光灯之外的所有区域都应迅速陷入深深的黑暗。
（阴影衰减严重），几乎与黑色背景融为一体。
不是柔光。
头发：长长的黑发，几缕发丝垂落在脸颊两侧。发梢应与阴影融为一体。
姿势：一只手轻轻抬起放在嘴唇上，做出羞涩、犹豫的姿态。
眼神神秘，直视镜头。
服装：黑色长袖针织毛衣；
毛衣和身体大部分应该融入黑暗中，细节越少越好。
整体基调：阴郁、忧郁、戏剧化、神秘。
只有面部受光部分具有高对比度。
聚光灯之外的一切都应该几乎隐形。
