Prompt
Create an image of a realistic portrait of Kirsten Flagstad, a renowned Norwegian opera singer, in a formal attire, possibly in a 1930s-1940s style, highlighting her elegant and powerful presence, with a subtle background that hints at her association with the opera, such as a faint image of an opera house or a musical score; the portrait should convey her dramatic soprano voice and her iconic roles such as Brünnhilde, Isolde, Elsa, Senta, and Leonore.
