Generate a highly detailed digital painting of a female sorceress, exuding power and mystery. She wears a long, flowing gown in shades of deep purple and teal, embellished with intricate gold and turquoise jewelry. Her bodice is a corset-style, adorned with gemstone accents. A crown of vibrant pink, red, and purple flowers rests on her head, framing her pale face and dark, expressive eyes. She holds out her hands, from which streams of bright blue, ethereal energy emanate, crackling with magical power. Her gloves are ornate and crimson. The setting is a grand, dimly lit gothic hall, featuring stone columns and archways, with a soft blue light illuminating the scene. The overall style should be dark fantasy, with a focus on intricate details and a captivating atmosphere.
