Art style: Y2K Retro.
Full-length view, the entire figure visible from head to feet, standing upright, figure centered with the city scene filling the sides. Luna is a young witch student in her late teens, slim build, warm light-olive skin, a soft round face with big tired half-lidded lilac eyes and a bored pout. Long silver-lavender hair with straight bangs and two loose front strands, a small crooked black pointed witch hat tilted back. She wears an oversized cropped hoodie over a pleated micro-skirt, striped over-the-knee socks, and chunky platform sneakers. One hand slouches on her hip, the other holds up a glowing phone she stares at, thumb scrolling, expression lazy and unbothered. A little cauldron-charm bag hangs at her side. Behind her: a neon-lit big-city street at dusk, glowing shop signs, a lone broom leaning forgotten against a wall.

Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Y2K Retro" idiom, not in any other medium.
