Prompt
Create an image of a dignified British composer from the early 20th century, sitting at a piano, with a sheet of music in front of him, surrounded by elegant furnishings. He is a middle-aged man with a slender build, wearing a suit and tie, with a kind face and a hint of a smile. In the background, there is a subtle hint of a classical music concert hall or a refined study. The style should be realistic, with muted colors and a sense of sophistication. The composer, Sir Lennox Berkeley, is lost in thought, reflecting on his musical creations, such as his Serenade for Strings or Symphony No. 1.
