收集末班地铁座椅记忆的软垫管理员：掀起一块旧坐垫

镜头采用方形中心构图被一条动作方向打破，主体周围不堆装饰符号，输出 1:1。最终图像作为社区修复日纪念插画。镜头进入末班地铁离开后的车厢，只讲收集末班地铁座椅记忆的软垫管理员掀起一块旧坐垫，放出两段不同乘客留下的温度轨迹这一件事。媒介为钢笔旅行速写与局部水彩晕染，线条允许犹豫和回勾，白纸保留大片空处，重点控制纸纤维、手撕边缘、叠层阴影和留白关系。材质细节限定为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。色光为雾粉、铁锈棕、深海蓝和玻璃青；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。动作层级：动作分层：前景清楚呈现「掀起一块旧坐垫」，中景以「放出两段不同乘客留下的温度轨迹」交代结果，两层之间不插入其他事件。让「收集末班地铁座椅记忆的软」的「掀起一块旧坐垫」直接导向「放出两段不同乘客留下的温度轨」；背景只解释「末班地铁离开后的车厢」。可见文字：画面完全无字，不出现数字、品牌、签名或水印。不模仿在世艺术家，不使用现成 IP、廉价塑料 3D、伪签名或水印。

Organize the 1:1 image through a square centered composition broken by one action direction, with no decorative symbols crowded around the subject. The final frame serves as a commemorative illustration for a community repair day. The subject is a cushion keeper collecting memories from last-train seats; the workplace is a train carriage after the final metro; the central action is lifts an old cushion and releases two heat trails left by different passengers. Render through pen travel sketching with local watercolor blooms, allowing hesitant hooks and generous untouched paper while maintaining paper fiber, hand-torn edges, layered shadow, and negative-space relationships. Materials touching the action must follow this rule: retain handmade marks at subject edges and keep the contact point clear, without unrelated decoration. Use this lighting and palette: fog pink, rust brown, deep-sea blue, and glass cyan; light and dark emerge from layers and negative space in the chosen handmade medium, without plastic gloss or photographic flare. Action direction: Keep the full action “lifts an old cushion and releases two heat trails left by different passengers” in one continuous plane, with its contact point and result both visible. Keep “a train carriage after the final metro” concrete while “a cushion keeper collecting memories from last-train” completes “lifts an old cushion and releases two heat trails” and resolves “lifts an old cushion and releases two heat trails”. Typography follows place no text, numerals, brands, signatures, or watermarks anywhere. Do not imitate a living artist or use existing IP, cheap plastic 3D, false signatures, or watermarks. 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 1:1; no variants, process sheet, split panels, mockup frame, or contact sheet.
