A detailed illustration of Sailor Saturn, a 6-year-old Japanese schoolgirl in a classroom setting, standing in front of a school building at night. She is wearing her sailor senshi uniform, complete with a purple sailor collar, miniskirt, white gloves, and a star choker. Her short purple hair is adorned with a circlet, brooch, earrings, and gloves. Her purple eyes are sparkling and full of life. The scene is lit by the moonlight, and the night sky is filled with stars. The image is rendered in high resolution with perfect lighting, extremely detailed CG, and beautiful, detailed eyes. The composition is a cowboy shot, and the overall style is a masterpiece.
