Prompt
"Generate a realistic portrait image of Margaret Beaufort, Countess of Richmond and Derby, in a 15th-century style, dressed in elegant attire befitting her nobility, set against a backdrop that subtly suggests her connection to education, possibly with a view of Cambridge in the distance or symbols of her founded colleges, Christ's College or St John's College, and incorporating elements that reflect her role as the mother of Henry VII and her significance in the Wars of the Roses."
