London Papercraft and Clay Diorama

Create a charming miniature 3D papercraft and clay-diorama illustration of {argument name="location" default="London, England"}, presented like a premium handcrafted souvenir postcard. Set the scene on a rounded cobblestone island over a warm off-white textured paper background. Feature miniature {argument name="landmarks" default="Big Ben and the Palace of Westminster, the London Eye, Tower Bridge"}, and classic red double-decker buses, surrounded by elegant Victorian architecture, narrow streets, tiny black cabs, and the River Thames flowing through the composition. Add miniature Londoners in stylish everyday British clothing, tiny Union Jack details, street lamps, flower planters, café tables, newspaper stands, red telephone booths, and subtle London street signs. Build everything from layered paper, molded clay, folded cardstock, and finely textured handmade materials. Include soft papercraft clouds above the skyline with a tiny airplane and a few birds drifting through the sky. Use warm cinematic lighting, gentle shadows, subtle depth of field, whimsical miniature proportions, intricate handcrafted details, and a sophisticated premium souvenir aesthetic. Compose the diorama from a slightly elevated three-quarter perspective, with a polished yet handmade feel and beautifully balanced visual density. Place elegant cursive lettering beneath the miniature diorama, integrated naturally into the postcard design.
