Create a realistic portrait of a 19th-century British novelist, specifically a middle-aged woman with a gentle and introspective expression, wearing attire typical of the Victorian era, sitting in a cozy study with books and papers around her, capturing the essence of Elizabeth Cleghorn Stevenson, also known as Elizabeth Gaskell, a renowned author of works such as "Mary Barton", "Cranford", "North and South", and "Wives and Daughters".
