Vampire Countess OVA Character Design

A beautiful adult woman, age 300+ but appearing 29, with aristocratic vampire countess energy, long black hair with soft crimson undertones, deep ruby eyes, and a tiny gold choker charm, designed as an original high-end 90s / early-2000s OVA anime character. Elegant hand-drawn cel animation style, refined mature facial proportions, luminous expressive eyes, soft natural blush, delicate lips, graceful jawline, detailed hair strands, subtle imperfect linework, warm analog color palette, cinematic cel shading, gentle film grain, painted texture, emotionally magnetic presence. She has a graceful feminine figure with tasteful cleavage, elegant posture, natural curves, and confident adult beauty. She wears a black velvet evening gown with an elegant low neckline, long lace gloves, antique earrings, layered dark fabric folds, and a red silk ribbon at the waist. Her pose is standing beside a tall window with one hand resting on the curtain, showing seductive restraint, loneliness, and ancient power. Sensual but refined, gothic OVA heroine energy, no explicit nudity, no modern glossy digital look. Background: moonlit mansion interior with candles, heavy curtains, and painted blue shadows.
