Generate a high-end illustrated poster in a 3:4 vertical format from the uploaded photograph, not a collage.
Divide the image strictly into equal upper and lower halves. Preserve the original photograph in the upper half: keep the subject, structure, realistic textures, natural light and shadow, and original atmosphere unchanged. Apply only subtle art-magazine-style photographic color grading. The background may be extended naturally, but do not distort the subject.
Reconstruct the photograph in the lower half as an endearingly clumsy Korean-style flat illustration: retain the subject's outline, action, relationships between objects, and narrative layout. Remove realistic lighting, perspective, and material textures. Use rounded geometric shapes, solid-color fills, and rough, wobbly, hand-drawn black lines. Keep it clearly recognizable but not realistic.
Use a limited, highly saturated palette extracted from the photograph, with large areas of bright, solid-color background and negative space. Give the composition a clear visual focal point, complemented by misalignment, overlap, variations in scale, and slight cropping. Avoid clutter, gradients, shadows, muddy color mixing, and a plastic appearance.
Finally, add a short English title and a small amount of English annotation. Arrange the text naturally along the subject, color blocks, or negative space. Slight rotation and misalignment are allowed so that the lettering becomes part of the image.
Overall feel: authentic photography, children's-picture-book-style flat illustration, an independent-publication poster, bright, childlike, friendly, and playful.
为上传照片生成一张3:4竖版高端插画海报，非拼贴
画面上下严格1:1分割。上半部分保留原照片：主体、结构、真实质感、自然光影和原有氛围不变，仅做轻微艺术杂志感摄影调色，可自然延展背景但不变形主体
下半部分将照片重构为笨拙可爱的韩式平面插画：保留主体轮廓、动作、物体关系和叙事布局，去除写实光影、透视和材质，用圆润几何形、纯色填充、粗糙抖动的手绘黑线表现，清晰可识别但不写实
插画使用从照片提取的高饱和有限色彩，大面积明亮纯色背景和负空间，构图有明确视觉中心，辅以错位、遮挡、大小变化和轻微裁切，避免杂乱、渐变、阴影、灰浊混色和塑料感
最后加入简短英文标题和少量英文注释，沿主体、色块或负空间自然排版，可轻微旋转和错位，使文字融入画面
整体感觉：真实摄影、儿童绘本式平面插画、独立出版物海报、明亮、童真、友好、俏皮
