创建一张高端的竖版旅行日记海报，采用精确的 50/50 上下分屏布局。

Create a premium vertical travel-journal poster in an exact 50/50 split. Top 50%: Keep the original reference photo completely real and unchanged same composition, architecture, people, colors, lighting, perspective, and details. Bottom 50%: Transform the same photo into a delicate hand-drawn colored-pencil + watercolor sketch on warm cream paper, with visible pencil strokes, soft washes, subtle paper grain, imperfect outlines, and gentle cross-hatching. Keep every subject recognizable. Add elegant handwritten text: “A Beautiful Day” above and “Memories to Keep” below. Minimal, nostalgic, sophisticated travel-magazine aesthetic. No extra objects, no photorealism in the bottom half, exact 50/50 layout.

创建一张高端的竖版旅行日记海报，采用精确的 50/50 上下分屏布局。 顶部 50%：完全保留原始参考照片的真实感与原貌，构图、建筑、人物、色彩、光线、透视和细节均保持不变。 底部 50%：将同一张照片转化为细腻的手绘风格作品，结合彩色铅笔与水彩，绘制在温暖的米色纸张上，可见铅笔笔触、柔和的水彩晕染、细微的纸张纹理、不完美的轮廓线以及轻柔的交叉排线。每一个主体仍需清晰可辨。 添加优雅的手写文字：“A Beautiful Day”置于上方，“Memories to Keep”置于下方。整体呈现极简、怀旧、考究的旅行杂志美学。不添加任何额外物体，底部一半不得出现照片级真实感效果，严格保持 50/50 的版式布局。
