Prompt
"Generate an image of a small, underground London railway station with a simple entrance and a classic London Underground sign reading 'Warwick Avenue'. The station should be depicted in a realistic style, with a minimalist exterior and a faded London Underground logo. The surrounding area should be a typical London street scene with buildings and a pavement, in a muted color palette. The image should convey a sense of a quiet, unassuming station in the heart of the city."
