复古双色调编辑插画

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.
