Character anime illustration, night scene, indoor, melancholic

Create an extremely detailed anime fantasy illustration depicting two astral mages sitting close together inside a starlit observatory. There are two characters in the scene: on the left, a young witch with long wavy hair and purple eyes; on the right, a young male mage with messy deep navy-blue hair and blue eyes. Both are curled up on the floor, knees together, leaning toward each other, with quiet and melancholic expressions, gazing at the viewer. Dress them in exquisite matching astral mage outfits, mainly in , black, silver, and gold: flowing embroidered cloaks covered with constellation patterns, with star chains, crescent moon pendants, jewel brooches, dangling star jewelry, ornate cuffs, lace trim, tall boots, layered shawls, and fine metalwork. The left character wears a huge pointed witch hat decorated with striking blue gems, starburst ornaments, silver chains, small stars, moons, and constellation embroidery. The right character wears a formal astral cloak with a gold-edged shoulder cape and hanging astrolabe-shaped ornaments. Place them in a magnificent magical observatory, with tall light-colored columns, arched golden celestial frames, hanging orreries, crescent moons, star pendants, armillary spheres, and glowing astrological rings. The floor is a dark blue glossy material, with glowing circular zodiac and constellation diagrams painted beneath. The background sky is deep indigo, filled with stars, planetary rings, moon phases, a huge crescent moon, half moon, and intricate circular star charts radiating behind the characters. Add a handwritten-signature-like text at the upper left. Use a high-precision gpt-image-2 anime art style: exquisite facial rendering, soft glowing shadows, intricate lines, jewel-like highlights, cool blue-purple color palette, sparkling magical particles, romantic gothic astral atmosphere, symmetrical composition, 4:5 vertical canvas, ultra-detailed accessories, no modern items, no watermark except for the small signature.
