Portrait orné d'une Magical Girl Émeraude

A highly polished anime magical-girl portrait in the style of a luxurious shoujo illustration, showing a confident teenage heroine inspired by a planet-themed sailor guardian. She stands in a three-quarter pose from mid-thigh up, centered, with her left hand on her hip and her right hand giving a thumbs-up. She has {argument name="hair color" default="warm chestnut brown"} hair styled in a very high, voluminous ponytail tied with 2 glossy green bead ornaments, with long flowing curls sweeping dramatically to the right. Her outfit is a classic sailor-style magical uniform with 5 clearly visible main clothing elements: a fitted white bodice, a deep emerald-green sailor collar, a large pink chest bow with a round green gem brooch at the center, a short pleated emerald-green skirt, and a large pink back bow visible at the waist. She also wears 4 visible accessories: 2 long white elbow gloves, 2 stacked emerald-green wrist bands, small pink gemstone stud earrings, and a green choker. Render the costume with glossy satin-like highlights and elegant reflective fabric. The character should project bravery, poise, and sparkling heroic charm. Place her against an ornate celestial fantasy background split diagonally into 2 contrasting zones: a dark midnight-blue galaxy field filled with stars, and a luminous iridescent crystal field with prismatic shimmer. Surround the scene with elaborate gold filigree lacework, hanging crystal chains, star pendants, jeweled ornaments, and large faceted gemstones. Include floral crystal decorations in the corners, especially layered translucent flowers and roses in lavender, violet, and icy blue tones. Fill the entire image with intense sparkle effects, lens-like starbursts, glitter dust, and jewel reflections. Use a rich palette of emerald green, blush pink, gold, sapphire, lavender, and pearl white. The composition should feel premium, radiant, ornate, and nostalgic, like a deluxe collector art print of {argument name="character theme" default="emerald planet guardian"}. Ultra-detailed anime illustration, crisp linework, glossy highlights, luminous shading, intricate decorative background, masterpiece quality, square composition.
