"Create a hyper-detailed 3D rendering and illustration design for a jute bag, featuring a London-themed central object such as Big Ben, the London Eye, or a vintage red phone booth. The design should have a vibrant urban feel with elements of London's skyline or street life in the background, rendered in ultra-high-definition (8K, UHD). Use soft lighting, possibly from the golden hour or nighttime city lights, to enhance textures and details. Include subtle HDR effects, vivid colors like red, blue, and yellow, and incorporate natural textures to complement the jute material. If including text, choose a clean sans-serif font and place it in a balanced position within the design, ensuring it integrates seamlessly with the visuals. The design should capture the modern yet nostalgic essence of London while maintaining a chic and stylish aesthetic."
