创作一幅惊艳的 4:5 竖版美术素描插画，描绘 [STRUCTURE NAME]，仿佛由一位大师级建筑艺术家在一本奢华旅行写生本中亲手…

Create a stunning 4:5 vertical fine-art sketch illustration of [STRUCTURE NAME] as if it is being drawn by a master architectural artist inside a luxury travel sketchbook. Show the famous structure transitioning from loose preliminary pencil lines into a fully detailed finished architectural drawing. The foreground should contain delicate construction lines, perspective guides, measurement marks, small handwritten architectural notes, compass marks, arrows, erased pencil strokes, and unfinished portions. As the eye moves toward the main structure, the sketch gradually becomes more refined — combining graphite pencil, fine black ink, subtle watercolor washes, cross-hatching, and delicate hand-drawn textures. Include small artistic studies around the main drawing: a tiny side elevation, architectural detail, window or ornament study, simplified map outline, and a small silhouette showing the scale of the structure. Use an elegant warm ivory sketchbook-paper background with natural paper fibers and subtle imperfections. Keep the composition sophisticated and spacious. The structure should remain the unmistakable hero. Add minimal handwritten-style labeling: [STRUCTURE NAME] [CITY, COUNTRY] ARCHITECTURAL STUDY The artwork should feel like an original museum-quality architectural sketch discovered inside an explorer’s personal sketchbook — artistic, intellectual, nostalgic, detailed, and highly collectible. No photorealistic rendering, no 3D CGI, no modern infographic boxes, no excessive text, no watermark.

创作一幅惊艳的 4:5 竖版美术素描插画，描绘 [STRUCTURE NAME]，仿佛由一位大师级建筑艺术家在一本奢华旅行写生本中亲手绘制。 呈现这座著名建筑从松散的初步铅笔线条，逐步过渡到完整、精细的建筑成稿的过程。 前景应包含细腻的辅助线、透视引导线、尺寸标注、细小的手写建筑笔记、指北针标记、箭头、擦除的铅笔笔触以及未完成的部分。 随着视线移向主体建筑，素描逐渐变得更为精致——结合石墨铅笔、精细黑墨、淡雅的水彩晕染、交叉排线以及细腻的手绘质感。 在主图周围加入小幅艺术研究图：一张微型的侧面立面图、建筑细部、窗或装饰构件研究、简化的地图轮廓，以及一个显示建筑尺度的小剪影。 采用优雅的暖象牙色写生本纸张背景，带有自然纸张纤维与微妙的瑕疵痕迹。 保持构图精致且留白充足，使建筑本身始终成为无可争议的主体。 添加极简的手写风格标注： [STRUCTURE NAME] [CITY, COUNTRY] ARCHITECTURAL STUDY 整幅作品应让人感觉像是在一位探险家的私人写生本中发现的原创博物馆级建筑素描——充满艺术性、智识感、怀旧氛围、细节丰富，且极具收藏价值。 不要写实渲染，不要 3D CGI，不要现代信息图表方框，不要过多文字，不要水印。
