从铅笔草线长成建筑的旅行速写本

A refined 4:5 vertical fine-art sketch illustration of [STRUCTURE NAME], drawn as if by a master architectural artist inside a luxury travel sketchbook. Let the famous structure pass from loose preliminary pencil lines into a fully worked, finished architectural drawing. In the foreground, place delicate construction lines, perspective guides, measurement marks, small handwritten architectural notes, compass marks, arrows, erased pencil strokes and unfinished passages. Toward the main structure the sketch grows steadily more refined, combining graphite pencil, fine black ink, subtle watercolor washes, cross-hatching and delicate hand-drawn textures. Around the principal drawing, add small artistic studies: a tiny side elevation, an architectural detail, a window or ornament study, a simplified map outline, and a small silhouette that shows the structure's scale. The ground is an elegant warm ivory sketchbook page with natural paper fibers and subtle imperfections. Keep the composition sophisticated and spacious, with the structure as the unmistakable hero. Add only minimal, handwritten-style labeling: [STRUCTURE NAME] [CITY, COUNTRY] ARCHITECTURAL STUDY The finished piece should read as an original museum-quality architectural sketch found in an explorer's personal sketchbook: artistic, intellectual, nostalgic, detailed and highly collectible. Avoid photorealistic rendering, 3D CGI, modern infographic boxes, excessive text and watermarks.

一幅精致的4:5竖版美术速写插画，主题是[STRUCTURE NAME]，仿佛由建筑绘图大师画在一本奢华的旅行速写本里。 让这座著名建筑从松散的铅笔起稿线，逐渐过渡成细节完整的成品建筑图。 前景放入细致的结构线、透视辅助线、测量标记、手写的小段建筑笔记、圆规痕迹、箭头、擦除的铅笔笔触和未完成的部分。 越靠近主体建筑，画面越精细，综合运用石墨铅笔、细黑墨线、淡淡的水彩渲染、交叉排线和细腻的手绘肌理。 在主图周围加入小幅艺术研究：一个微缩的侧立面、一处建筑细节、一个窗或装饰纹样的研究、一张简化的地图轮廓，以及一个显示建筑尺度的小剪影。 底纸是雅致的暖象牙色速写本纸张，带有自然纸纤维和细微瑕疵。 构图保持考究而疏朗，建筑始终是毫无疑问的主角。 只添加极少的手写风格标注： [STRUCTURE NAME] [CITY, COUNTRY] ARCHITECTURAL STUDY 成品要像探险家私人速写本里发现的原创博物馆级建筑速写：艺术、理性、怀旧、细节丰富、极具收藏价值。 避免照片级渲染、3D CGI、现代信息图方框、过多文字和水印。
