Korean Graffiti Illustration Portrait

Based on the user-uploaded photo, create a Korean-style hand-drawn graffiti illustration character poster. Retain the person's real identity features and overall temperament, but the overall presentation should be clearly slanted towards illustration rather than realistic redrawing.

Style Reference: Korean semi-realistic illustration, distinct character feel, natural and expressive facial emotions, half-body composition, slight dynamic poses. Emphasize loose, spontaneous hand-drawn lines, black ink outlines, ink splatters, sketch-like strokes, visible brush textures, and a blend of soft pastel tones and ink shadows, presenting a manga-sketch-like texture.

Do not make it a highly realistic illustration; do not make it look too much like a photo. It should have more of a "drawn" feel, with free lines, loose edges, and partial areas feeling slightly unfinished. Hair and clothing details should be rich, and the overall look should be exquisite yet with a casual graffiti vibe.

Keep the background simple, such as pure white or light-colored paper texture, and freely add a few symbolic decorative elements around the character like handwritten short phrases, stars, hearts, arrows, ink dots, small stickers. Please let the copywriting and background atmosphere develop freely based on the character's temperament. The overall result should be high-end, light, and agile, like a Korean-style hand-drawn character poster that would go viral on X.

Original-Prompt

请基于用户上传的照片，创作一张韩风手绘涂鸦插画感人物海报。保留人物真实身份特征与整体气质，但整体表现要明显偏插画化，而不是写实转绘。

风格参考：韩风半写实插图、鲜明角色感、自然有表现力的面部情绪、半身构图、轻微动态姿势。强调松散自发的手绘线条、黑色墨水勾线、墨迹飞溅、草稿感笔触、可见笔刷纹理，以及柔和粉彩色调与墨水阴影的混合，呈现漫画草图般的质感。

不要做成高度写实插画，不要太像照片。要更有“画出来”的感觉，线条自由、边缘松弛、局部略带未完成感，头发和服装细节丰富，整体精致但有随性涂鸦感。

背景保持简约，可以是纯白或浅色纸张质感，围绕人物自由加入少量手写短句、星星、爱心、箭头、墨点、小贴纸等象征性装饰元素。文案和背景氛围请根据人物气质自由发挥。整体要高级、轻盈、灵动，像 X 上会火的韩系手绘人物海报。
