提示词
杰作级现代编辑风半矢量插画，带手工绘制的表现力线条，融合大胆的平面设计美学与有机的墨水素描能量。使用一套受限的复古双色调配色渲染，由{argument name="base colors" default="warm cream (#F2DFC0), muted ivory, charcoal navy (#243647), slate gray, cool gray"}组成，以及{argument name="accent color" default="vivid burnt orange (#F57A2A)"}作为唯一的强调色。保持精确的色彩和谐，配高对比度的扁平图形阴影和微妙的色调分层。
创造干净、简化的几何阴影平面，带不规则的棱角形状，同时保留松散的手绘不完美感。轮廓线具有富有表现力的、带压力变化的粗细笔触，在粗轮廓线和精细的素描线之间交替。避免完全均匀的矢量路径；每一条线都应该感觉是自然手绘的，带轻微的摆动、渐细的末端和可见的笔触节奏。
面部特征用分层的图形色块和即兴的素描线条结合塑造，在写实和插画之间取得平衡。头发和胡须由数百笔充满活力、流动的笔触构成，重叠的曲线墨水般笔痕、松散的涂鸦、渐细的发丝，以及有质感的簇状，保持一种有机手工的观感，而不是光滑的数码渲染。
在整张脸和衣服上，使用极简但有意为之的横切轮廓标记、细微的划痕质感、微小的构造线，以及散落的表现力素描笔触。阴影由扁平色块构成，偶尔带有质感边缘和细细的内部轮廓线，在不使用照片级渐变的情况下保留深度感。
背景是纯色的{argument name="background color" default="warm cream"}，没有场景元素，除极其细微的纸张纹理外没有其他质感。整体风格类似一张高级当代平面肖像海报，融合半矢量的精确性与富有表现力的墨水绘画、大胆的编辑构图、手工的不完美感、图形化的阴影设计、有机的线条变化，以及清晰的高分辨率插画质感。
负面风格：照片级写实、光泽渲染、喷绘渐变、水彩、油画、3D 渲染、漫画网点、过度平滑的矢量曲线、过多质感、霓虹色、过饱和的彩虹配色、模糊边缘、统一的线宽、扁平无生气的笔触。原文提示词（English）
Masterpiece modern editorial semi-vector illustration with handcrafted expressive linework, combining bold graphic design aesthetics and organic ink-sketch energy. Render using a limited retro duotone palette consisting of {argument name="base colors" default="warm cream (#F2DFC0), muted ivory, charcoal navy (#243647), slate gray, cool gray"}, and {argument name="accent color" default="vivid burnt orange (#F57A2A)"} as the only accent color. Preserve the exact color harmony with high-contrast flat graphic shadows and subtle tonal layering.
Create clean, simplified geometric shadow planes with irregular angular shapes, while retaining loose hand-drawn imperfections. Outlines feature expressive pressure-sensitive thick-and-thin strokes, alternating between bold contour lines and delicate hairline sketch marks. Avoid perfectly uniform vector paths; every line should feel naturally drawn by hand with slight wobble, tapering ends, and visible stroke rhythm.
Facial features are modeled using layered graphic shapes mixed with spontaneous sketch lines, giving a balance between realism and illustration. Hair and beard are built from hundreds of energetic flowing strokes, overlapping curved ink-like marks, loose scribbles, tapered strands, and textured clusters, maintaining an organic handcrafted appearance rather than smooth digital rendering.
Use minimal yet intentional cross-contour marks, subtle scratch textures, tiny construction lines, and scattered expressive sketch strokes throughout the face and clothing. Shadows are composed of flat color blocks with occasional textured edges and thin internal contour lines to preserve depth without photorealistic gradients.
Background is a solid {argument name="background color" default="warm cream"} with no scenery, no texture except extremely subtle paper grain. Overall style resembles a premium contemporary graphic portrait poster, blending semi-vector precision with expressive ink drawing, bold editorial composition, handcrafted imperfections, graphic shadow design, organic line variation, and crisp high-resolution illustration.
Negative style: photorealism, glossy rendering, airbrush gradients, watercolor, oil paint, 3D rendering, comic halftone dots, overly smooth vector curves, excessive texture, neon colors, saturated rainbow palette, blurry edges, uniform line weight, flat lifeless strokes.建议模型
