Prompt
"Create a realistic portrait of William Ewart Gladstone, a prominent 19th-century British politician, in a formal Victorian-era setting. He should be depicted wearing a well-tailored suit and holding a book or papers, conveying his intellectual and literary pursuits. Incorporate subtle hints of his four terms as Prime Minister and his notable contributions to education, civil service, and Irish Home Rule. The style should reflect the realism of John Everett Millais or George Frederic Watts, who famously painted him. Include a dignified and introspective expression, capturing his influential personality."
