從鉛筆草線長成建築的旅行速寫本

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.

一幅精緻的4:5豎版美術速寫插畫，主題是[STRUCTURE NAME]，彷彿由建築繪圖大師畫在一本奢華的旅行速寫本里。 讓這座著名建築從鬆散的鉛筆起稿線，逐漸過渡成細節完整的成品建築圖。 前景放入細緻的結構線、透視輔助線、測量標記、手寫的小段建築筆記、圓規痕跡、箭頭、擦除的鉛筆筆觸和未完成的部分。 越靠近主體建築，畫面越精細，綜合運用石墨鉛筆、細黑墨線、淡淡的水彩渲染、交叉排線和細膩的手繪肌理。 在主圖周圍加入小幅藝術研究：一個微縮的側立面、一處建築細節、一個窗或裝飾紋樣的研究、一張簡化的地圖輪廓，以及一個顯示建築尺度的小剪影。 底紙是雅緻的暖象牙色速寫本紙張，帶有自然紙纖維和細微瑕疵。 構圖保持考究而疏朗，建築始終是毫無疑問的主角。 只新增極少的手寫風格標註： [STRUCTURE NAME] [CITY, COUNTRY] ARCHITECTURAL STUDY 成品要像探險傢俬人速寫本里發現的原創博物館級建築速寫：藝術、理性、懷舊、細節豐富、極具收藏價值。 避免照片級渲染、3D CGI、現代資訊圖方框、過多文字和水印。
