This mysterious woman stands tall in her long, black gown and pointed black hat against a background of imposing grey clouds. She is poised to cast a spell, her wand and broomstick adding to her powerful presence. Her slender frame and commanding gaze demand respect and awe, adding to the drama of the scene. To bring her and her mighty, mystical world to life, use shades of black and purple for the gown and hat, adding pops of silver and gold for a sparkling effect. The stormy sky could benefit from some foggy blues, grays and whites, with a touch of pink in the clouds to suggest a magical glow. To complete the image, some shadows of greens and tans could add dimension and realism.
