Prompt
Generate an image of a portrait of Richard Westall, a British painter, in a realistic style, depicting him as a middle-aged man with a gentle expression, wearing attire typical of the late 18th or early 19th century, set against a backdrop that subtly hints at his artistic profession, such as a canvas, brushes, or a palette in the background, reflecting his contributions to portrait, painting, and illustration, including his notable works like portraits of Lord Byron, illustrations for John Milton's Paradise Lost, and Sir Walter Scott's works, in a manner befitting a Royal Academy member who taught Queen Victoria.
