中文提示词
创作一张 8K 高细节的风格化数字肖像插画，人物表情略带愉悦，神情温和上扬，保持真实的脸部结构和自然的瑕疵，采用平视视角，主体直视镜头。 使用上传的图片作为主要的身份参考。 面部准确度（关键）： 确保面部身份准确度达到 100%。保留精确的脸部结构、骨骼解剖、修饰细节、下颌线、颧骨和额头比例。 主体与表情： 人物拥有自然的眼睛，可见虹膜细节。额头有明显的抬头纹。表情显得温和而内省，眼周带有淡淡的、放松的柔和感，嘴角有非常细微、自然的笑意——不要夸张，只需在保持写实感的同时呈现出轻微的情绪上扬。 发型： 自然长度、自然发色，略显自然凌乱，带有浅色调的纹理发丝，以增加深度和体积感。 服装： 身穿深绿色和棕色格子（苏丹格纹）夹克，带有宽松的绘画感图案。内搭一件素雅的米色/棕褐色衬衫，领口整齐。服装应显得质朴、简约且略带磨损感。 构图与取景（重要）： 仅限头部和肩部肖像（非全身） 主体在画面中完美居中 肩膀不得触碰边缘——保持干净的留白空间 画面底部应淡化为柔和、粗糙的绘画边缘（微妙的剪影感） 肖像下方留有负空间，将视觉焦点向上引导至面部 背景： 极简奶油色背景。在头部后方放置一个带有略微粗糙绘画边缘的醒目橙色方块，以形成对比和类似光环的框架效果。 光照： 来自左上方的柔和定向光，在额头、鼻梁和脸颊上营造出柔和的高光，并在对侧产生微妙的阴影，以增强面部结构和深度。 风格与渲染： 半写实插画，融合了编辑肖像艺术和图像小说风格 强烈的素描感线条，笔触富有表现力 可见的纹理笔触和绘画感阴影 干画笔效果，特别是在肩膀周围，图像在此处柔和地消融 自然的皮肤纹理，色调丰富（微妙的红色、中性色调，以及胡茬处淡淡的蓝色底色） 拒绝美颜——保留原始的真实感和瑕疵 质量标签： 超细节，8K 高分辨率，清晰对焦，纹理笔触，电影感肖像，居中构图，高级插画风格 长宽比 4:5
原始提示词
Create an 8k high-detail stylized digital portrait illustration of a person with a slightly happy, gently uplifted expression, maintaining realistic facial structure and natural imperfections, captured at an eye-level camera angle with the subject looking directly into the camera. Use the uploaded image as the primary identity reference. Face Accuracy (Critical) Match the face with 100% identity accuracy. Preserve exact facial structure, bone anatomy, grooming details, jawline, cheekbones, and forehead proportions. Subject & Expression: The person has natural eyes with visible iris details. His face shows noticeable forehead lines. His expression feels subtly warm and introspective, with a faint, relaxed softness around the eyes and a very slight, natural hint of a smile — not exaggerated, just a mild uplift in mood while preserving realism. Hair: Natural-length, natural colour hair, slightly naturally messy, with textured strands highlighted in lighter colour tones to add depth and volume. Outfit: He wears a dark green and brown plaid (tartan) jacket with a loose, painterly pattern. Underneath is a muted beige/tan button-down shirt with a neatly tucked collar. The clothing should feel grounded, simple, and slightly worn. Composition & Framing (IMPORTANT): Head-and-shoulders portrait only (no full body) Subject perfectly centered in the frame Shoulders must NOT touch the edges — maintain clean breathing space Bottom of the artwork should fade into a soft, rough, painterly edge (subtle cut-out feel) Negative space below the portrait to draw focus upward to the face Background: Minimal cream background. Behind the head, place a bold orange square with slightly rough, painterly edges to create contrast and a halo-like framing effect. Lighting: Soft directional lighting from the upper left, creating gentle highlights on the forehead, nose bridge, and cheek, with subtle shadows on the opposite side to enhance facial structure and depth. Style & Rendering: Semi-realistic illustration blending editorial portrait art and graphic novel style Strong sketch-like linework with expressive strokes Visible textured brushwork and painterly shading Dry brush effects, especially around the shoulders, where the image softly dissolves Natural skin texture with varied tones (subtle reds, neutral hues, faint bluish undertones for stubble effect) No beautification — preserve raw realism and imperfections Quality Tags: ultra-detailed, 8k high resolution, sharp focus, textured brush strokes, cinematic portrait, centered composition, premium illustration style Aspect ratio 4:5
