Miniature London Paper-Craft Diorama

Create a delicate miniature paper-craft travel diorama of {argument name="city name" default="London"} on a vertical portrait canvas with lots of empty white textured watercolor-paper background. Place a tiny horizontal handmade paper stage slightly below center, showing exactly 14 recognizable elements: 1 red British telephone booth on the far left, 1 black vintage street lamp, 1 London Eye ferris wheel, 1 small pale green tree, 1 Big Ben clock tower, 1 Houses of Parliament building cluster, 1 small Union Jack flag, 1 Tower Bridge with two towers and blue suspension details, 1 red double-decker bus labeled “LONDON” on the bridge at the right, 1 leafy green tree at the far right, 1 stone bridge/embankment under the scene, 1 blue watercolor River Thames patch, 1 small white-and-navy boat with a tiny red flag on the water, and 1 dotted decorative travel path extending across the scene. Add exactly 3 doodle clouds in the sky area, exactly 3 simple flying bird silhouettes on the right, and exactly 1 tiny airplane above Big Ben following a dashed curved flight path. Use a whimsical handcrafted layered-paper look with soft shadows, fine ink outlines, subtle watercolor washes, muted cream, tan, blue, green, red and black tones, and a cozy travel scrapbook aesthetic. Under the river, center the handwritten caption “{argument name="caption text" default="London"}” followed by a small red heart. Keep the composition minimal, airy, and charming, with no extra text, no people, no watermark, and strong emphasis on tiny cut-paper detail against the blank paper background.
