宠物照片转复古包装对比海报

Turn the pet photo I uploaded into a 3:4 vertical comparison poster. The top half should directly keep the original photo I uploaded, maintaining a realistic photography texture, without changing the subject, redrawing, changing the scene, or altering the composition. The bottom half should convert the pet and scene from the same photo into a vintage matchbox illustration / old pet food packaging / old advertisement poster style. The overall design should use a limited color palette of beige old paper background + faded red + deep blue or dark green, with old paper texture, worn edges, printing grain, and slight registration offset. The bottom half should include a small amount of vintage English titles, decorative text, circular badges, and a bottom slogan. The text content should be automatically generated based on the pet's image, temperament, and scene in the photo, with the overall layout looking like an old packaging cover. Key point: The bottom half should not be too full, it should have borders, white space, and a sense of breathing, overall clean, vintage, cute, and collectible.

将我上传的宠物照片制作成一张 3:4 竖版上下对照海报。

上半部分 直接保留我上传的原始照片，保持真实摄影质感，不改动主体，不重画，不换场景，不改变构图。

下半部分 将同一张照片中的宠物与场景，转换成 复古火柴盒插画 / 老宠物食品包装 / 旧广告海报 风格。
整体使用 米黄色旧纸底色 + 褪色红 + 深蓝或墨绿 的有限配色，带有 旧纸纹理、磨损边缘、印刷颗粒、轻微套印偏移。
下半部分加入少量 复古英文标题、装饰文字、圆形 badge 和底部 slogan，文字内容根据照片中的 宠物形象、气质和场景自动生成，整体排版像老包装封面。

重点： 下半部分不要太满，要有 边框、留白和呼吸感，整体干净、复古、可爱、有收藏感。
