用彩线缝合人行道裂缝的城市修补匠：跨过裂缝拉紧最后一针

交付目标是社区修复日纪念插画。主体为用彩线缝合人行道裂缝的城市修补匠，位于刚完成步行改造的社区街角，正在跨过裂缝拉紧最后一针，路人从两侧同时踩下测试。色光为砂岩色、烟青、松针绿和琥珀高光；亮暗由所选手工媒介的叠层和留白形成，不使用塑料高光或摄影光斑。比例定为 4:5，视线通过4:5 单幅叙事构图，动作点位于下方三分线，周围留出媒介纹理的呼吸区抵达动作轮廓与媒介边缘。画面语言为细密针脚、棉线绒毛与布面起伏构成立体刺绣插画，背面线头可见一角，重点是线材张力、针脚节奏、布面层次和动作轮廓。动作相关材质：主体边缘保留手工媒介痕迹，动作接触处清楚，不增加无关装饰。动作阅读顺序：动作分层：前景清楚呈现「跨过裂缝拉紧最后一针」，中景以「路人从两侧同时踩下测试」交代结果，两层之间不插入其他事件。让「用彩线缝合人行道裂缝的城」的「跨过裂缝拉紧最后一针」直接导向「路人从两侧同时踩下测试」；背景只解释「刚完成步行改造的社区街角」。文字仅按画面完全无字，不出现数字、品牌、签名或水印处理。排除套模板边框、无关图标、复制角色、乱码和品牌符号。

Create a commemorative illustration for a community repair day. The subject is an urban mender stitching sidewalk cracks with colored thread; the workplace is a neighborhood corner just after pedestrian improvements; the central action is pulls the final stitch across a crack while passersby test it from both sides. Use only this color-light system: sandstone, smoky teal, pine green, and amber highlights; light and dark emerge from layers and negative space in the chosen handmade medium, without plastic gloss or photographic flare. Build the composition as a 4:5 single-frame narrative with the action on the lower third and breathing space for the medium texture, output in 4:5. Use dense stitches, cotton fuzz, and cloth relief forming an embroidered illustration, with a glimpse of loose thread on the reverse; thread tension, stitch rhythm, textile layers, and action silhouette must remain clear and credible. Treat the main working objects as follows: retain handmade marks at subject edges and keep the contact point clear, without unrelated decoration. Expand only this action: Stage the action in two layers: show “pulls the final stitch across a crack” clearly in the foreground, then use “passersby test it from both sides” in the middle plane as the consequence, with no unrelated event between them. Keep “a neighborhood corner just after pedestrian improvements” concrete while “an urban mender stitching sidewalk cracks with” completes “pulls the final stitch across a crack” and resolves “passersby test it from both sides”. Typography: place no text, numerals, brands, signatures, or watermarks anywhere. Also apply this exclusion: Exclude template borders, unrelated icons, copied characters, garbled text, and brand symbols. Final art direction: original handmade mixed-media illustration with matte mineral pigments and visible paper fibers. Use this controlled palette as the dominant visual system: #D8C18E, #657A52, #6D6A63, #E6A07A; preserve believable local material colors within it. Keep any text absent or minimal unless the source brief explicitly requires it; never add logos, signatures, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 4:5; no variants, process sheet, split panels, mockup frame, or contact sheet.
