"subject": {
"primary_subject": "A large-scale, intricate chalk drawing of Boa Hancock from 'One Piece' on a standard green classroom blackboard.",
"visual_details": "The illustration depicts Boa Hancock in a commanding pose, positioned centrally on the board. She is drawn with her signature long, straight black hair with a hime cut, rendered using dense application of black chalk with white accents for sheen. Her expression is haughty and imperious, with detailed dark blue eyes. She is depicted forming a heart shape with her hands, referencing her 'Mero Mero Mellow' technique. She wears a revealing red blouse with purple geometric patterns and gold snake-shaped earrings, drawn with vibrant colored chalks.",
"medium_texture": "The image preserves the dusty, matte quality of the chalk. Visible hatching and cross-hatching strokes create shading on her clothing and hair. Smudged areas on the green slate indicate where colors have been blended by hand.",
"surrounding_elements": "To the right of the character, vertical Japanese text reading '海賊女帝' (Pirate Empress) is written in crisp white chalk."

“主题”： {
“primary_subject”: “一幅绘制在标准绿色教室黑板上的大型、精细的《海贼王》角色波雅·汉库克的粉笔画。”
“视觉细节”： “这幅插画描绘了波雅·汉库克，她以威严的姿态位于画面中央。她标志性的黑色长直发，采用姬发式剪裁，以浓重的黑色粉笔绘制，并以白色点缀以增加光泽。她的表情傲慢而威严，深蓝色的眼睛刻画入微。她双手比划成心形，象征着她的‘Mero Mero Mellow’（柔情蜜意）技巧。她身着一件饰有紫色几何图案的性感红色上衣，佩戴着以鲜艳彩色粉笔绘制的金色蛇形耳环。”
“medium_texture”：图像保留了粉笔的粉尘质感和哑光效果。清晰可见的排线和交叉线笔触在她的衣服和头发上营造出阴影。绿色石板上的晕染区域表明了手工调色的位置。
