Neon Chibi Sailor Salute

Create a full-body 3D stylized chibi anime girl figurine on a pure black background, centered in a vertical portrait canvas. The character is {argument name="character name" default="Oyagi"}, a cute sailor-uniform schoolgirl with oversized rounded proportions, soft toy-like sculpting, blank glossy circular eyes without pupils, a tiny nose, and a gentle smiling expression. She is leaning forward playfully with legs spread wide, one hand raised horizontally to her forehead in a cheerful salute, and the other arm bent back at her side. Give her thick fluffy bobbed hair with large rounded bangs and side curls, rendered in a luminous {argument name="hair color" default="pink, violet, and cyan gradient"}. Dress her in a puffy Japanese sailor school uniform with a wide collar, bow knot and two hanging ribbon tails, pleated skirt, long socks or tights, slouchy ankle warmers, and rounded Mary Jane shoes; keep all clothing soft, inflated, and clay-like. Use vibrant iridescent lighting in {argument name="color palette" default="neon pink, magenta, violet, blue, cyan, and peach"}, with smooth subsurface scattering, glossy plastic-clay material, soft bloom, strong rim highlights, and no hard outlines. The pose should feel like a friendly morning greeting, energetic and cute, shot from a slightly low front angle so the head and raised hand dominate the upper frame while both shoes are visible near the bottom. Add a small elegant handwritten signature and date in the bottom-right corner reading {argument name="date text" default="July 26, 2026"} and {argument name="signature text" default="Oyagi"}. Avoid extra characters, scenery, props, pupils, realistic skin texture, or text other than the small signature/date.
