How create a fantastical miniature world with Gemini Nano Banana

A highly detailed, fantastical miniature world of London, featuring the iconic Clock Tower (Big Ben), Tower Bridge, and surrounding streets, an overcast and slightly rainy
English weather, people walking with umbrellas, red telephone
booths, double-decker red buses, and the misty silhouette of
the River Thames, emerging from the pages of an open, ancient
book. The scene is set on a classic, dark polished wooden
vintage desk, surrounded by an old map, a magnifying glass,
and a cup of hot tea.
The lighting is soft, diffused, and cool-toned (overcast/rainy
daylight), casting subtle, elongated shadows, creating a classic,
majestic, and magical misty atmosphere. The pages of the open
book feature visible, blurred script or text, which gracefully fades
into the central miniature. Cinematic composition,
hyper-detailed, depth of field (bokeh), with a low, close-up
perspective to emphasize the miniature scale. Subtle, glowing
mist and delicate light particles enhancing the classic fairytale
effect without being artificial. Photorealistic, 8k, highly rendered.
Aspect Ratio: 3:4 (vertical).
