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.
