Prompt
                                        
                                            Create a realistic portrait of a British novelist, set in a study or library with subtle nautical elements in the background, reflecting his time in the Royal Navy. The subject, a dignified man in his later years, with a gentle yet authoritative expression, should be seated with one of his notable works, such as "Lord of the Flies," casually placed in front of him. The style should be photorealistic, capturing the depth and complexity of his personality and literary contributions.
