Train Window Sketch Day

Create a “Train Window Sketch Day” poster in a 1:1 frame for a small public culture event. Organize the narrative around a train window cutting the passing view into four consecutive sketches, exposing material thickness and the contact surface instead of reducing opacity. Make image and typography share an asymmetric vertical composition; do not park text outside the artwork. Keep only four copy groups: “Train Window Sketch Day,” “Bring warmth to shared space,” “the north hall of the former waterworks,” and “check in ten minutes early.” The hero may cover one stroke edge only. Restrict secondary objects to directional arrows, handwritten slips, and material samples. Use woodcut linework on warm cotton paper to show process order and charcoal, ivory, verdigris, and coral pink as the complete color system. Build volume with a hooded overhead lamp, keeping the clearest shadow near the seam and the background quiet. Show no presentation environment beyond the trim. Exclude real brands, public figures, existing IP, device shells, and mirrored dimensional headlines. For the final rendering, make the subject change state without losing its original identity: a train window cutting the passing view into four consecutive sketches. Keep the source object recognizable at the point where it changes, and reveal one seam that explains the construction. At thumbnail size, the silhouette should still communicate the event before any small copy is read. Final art direction: editorial poster design with a disciplined grid and material-aware composition. Use this controlled palette as the dominant visual system: #F2EBDD, #243447, #C65D48, #D6A14B; preserve believable local material colors within it. Preserve the requested text hierarchy and wording as part of the design, but do not invent extra slogans, pseudo-text, logos, 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.

生成一张「火车窗景速写」海报，画幅 1:1，用于一场小型公共文化活动。围绕“火车窗连续切出四段速写”组织全部叙事，材料厚度与接触面清楚可见，不能靠降低透明度融合。主视觉和排版共同服从偏心竖构图，不要把文字贴在图像之外，让“火车窗连续切出四段速写”保持第一视觉中心。海报只保留四组文字：「火车窗景速写」「让公共空间拥有温度」「旧水厂北厅」「提前十分钟签到」，标题仅允许一处边缘遮挡。次级物件限定为导向箭头、手写纸条和材料样本，只为“火车窗连续切出四段速写”提供尺度参照。通过木刻线条与暖白棉纸表现工艺先后，整体色组为炭黑、象牙白、铜绿与珊瑚粉。带遮光罩的顶灯建立画面体积，接缝附近保留最清楚的落影，背景保持安静。裁切区外不保留陈列场景，文字完整。禁止真实品牌、公众人物、现成 IP、设备外壳与镜面立体标题，保持「火车窗景速写」的公共活动语气。
