Migratory Bird Post Office

Output a finished 2:3 “Migratory Bird Post Office” poster for a realistically small event. Center the image on a mailbox covered with handwritten addresses growing the wings of a returning migratory bird. The objects physically touch and deform, with no second visual gimmick. Choose an asymmetric vertical composition as the layout skeleton and move naturally from hero to text. Write “Migratory Bird Post Office,” “Turn participation into a practice that can continue,” “the riverside observation deck,” and “wear nonslip shoes and bring a pencil” accurately, with no pseudo-text or extra slogan. Limit supporting matter to true-scale specimens, wind-direction lines, and moisture. Use two-color screen printing with thin mineral-pigment layers for ink absorption, impressions, folds, and edge wear, with a palette of bread gold, coffee brown, midnight blue, and mint. Build volume with diffuse overcast daylight, keeping the clearest shadow near the seam and the background quiet. Keep headline, secondary line, and venue within trim safety. Remove mockups, sponsor logos, public figures, character assets, and excess lighting. For the final rendering, keep the metaphor literal enough to be built and photographed: a mailbox covered with handwritten addresses growing the wings of a returning migratory bird. Let the transition cross one focal plane so the viewer can understand it immediately at poster distance. End the image at the printed edge, with no wall, frame, clip, or presentation shadow. 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 2:3; no variants, process sheet, split panels, mockup frame, or contact sheet.

输出「候鸟归来邮局」海报成片，画幅 2:3，对应真实可举办的小型活动。画面中心呈现“贴满手写地址的信箱长出候鸟翅膀”，物件要真的接触并产生形变，不增加第二个视觉噱头。选择偏心竖构图作为版式骨架，使视觉从主物自然过渡到文字，让“贴满手写地址的信箱长出候鸟翅膀”保持第一视觉中心。文字区域逐字呈现「候鸟归来邮局」「把参与变成可延续的方法」「临河观察台」「穿防滑鞋并带铅笔」，不生成伪字或额外口号。辅物仅有真实比例标本、风向线和水汽。使用双色丝网印刷与矿物颜料薄层表现吸墨、压痕、折面和边缘磨损，配色限制为面包金、咖啡褐、午夜蓝与薄荷。阴天漫射天光建立画面体积，接缝附近保留最清楚的落影，背景保持安静。把标题、副句和地点放在安全边内。去掉样机、赞助 Logo、公众人物、角色资产和多余光效，保持「候鸟归来邮局」的公共活动语气。
