Create a highly detailed, realistic, full-body image of a character with the following features: a young woman with an energetic and powerful stance, showcasing her as a charismatic rockstar. Her hair is dark blue, styled in a short, modern fashion. She has bright blue eyes, exuding confidence. She wears a white armored top with icy blue accents that suggest a thematic connection to ice powers. She has matching gauntlets and fishnet stockings. Her wings are stylized, resembling delicate ice formations. In her hands, she holds an instrument shaped in a unique design, reminiscent of fantastical weaponry, but clearly a stage prop for her performances. Her attire includes a silver skirt and stylish combat boots. The background is a gradient from icy blue to soft white, underscoring her persona as an artist with a powerful presence and a touch of fantasy.
