Create a highly detailed and realistic model train diorama. The central subject should be rendered as a perfectly scaled, miniature figure, thoughtfully positioned within the miniature landscape. This intricate landscape must include: 1. Terrain: Rolling miniature hills, flowing rivers, and finely textured ground cover. 2. Vegetation: Lush, tiny trees, bushes, and meticulously placed foliage. 3. Structures: Miniature buildings, bridges, and other architectural elements appropriate for a diorama. 4. Trains & Tracks: Multiple model trains, some in motion, traveling on intricately laid tracks, complete with tiny railway details. Ensure the entire scene exhibits a photographic quality, with realistic lighting, sharp focus on the miniature elements, and a shallow depth of field (tilt-shift effect) to strongly convey the miniature scale and immersive diorama aesthetic.
