Prompt
Create an image of a British classical music composer and conductor, sitting at a piano, with a sheet of music in front of him, wearing a suit and tie, with a thoughtful expression, in a style reminiscent of a 20th-century portrait, inspired by the works of artists such as Rex Whistler or Graham Sutherland, who often depicted notable figures of their time; the composer, William Walton, should be middle-aged, with a distinguished look, in a setting that reflects his connection to classical music and his notable works, such as "Façade" and "Symphony No. 1".
