Moonlit Gothic Mansion Anime Cover

Create a vertical anime album-cover illustration in monochrome indigo-blue and antique ivory, like an intricate pen-and-ink etching on aged paper. The scene shows {argument name="character name" default="a young blond man"} leaning out of the central open window of an abandoned classical mansion at night. He has tousled pale blond hair, soft blue-gray eyes, a calm faint smile, and rests his cheek on one hand with the other arm folded on the windowsill. Dress him in a neat dark three-piece suit with a white shirt and tie, elegant but slightly melancholic. The mansion facade is symmetrical and highly detailed: a triangular pediment with a small spire at the top, ornate cornices, tall rectangular window frames, weathered stone or brick texture, and two boarded-up side windows with diagonal wooden planks. The open central window reveals a dim interior with hints of chandelier and old room details. Surround the building with dense dark foliage and leafy branches framing the left, right, and bottom edges. Above the roof, place a bright full moon partly surrounded by wispy clouds in a starry deep navy sky. Use delicate cross-hatching, fine architectural linework, subtle paper grain, high contrast moonlight, and a romantic gothic mood. No visible title text, no logo, no watermark; compose for a 9:16 cover image with the character centered in the lower-middle window and the moon near the upper right.
