Full-body 2D anime-style illustration of a beautiful blonde girl

Full-body 2D anime-style illustration of a beautiful blonde girl with long hair tied into high twin ponytails, bright blue eyes, and a determined expression. She is wearing an elegant off-shoulder black dress with frilled edges, a delicate lace choker, and black gloves. She also has black or dark brown thigh-high stockings. She stands in a confident pose, slightly leaning forward or making an expressive hand gesture as if speaking passionately. The artwork should have detailed hair strands, smooth skin tones, crisp line art, and vibrant colors, in the style of modern high-quality anime art. The background should be a simple dark gradient to make the character stand out.
