Portrait Anime Illustration Cool-Tone Dark Elegant

An exquisite anime illustration depicting a tall adult demon woman, presenting a calm, elegant full-body portrait. She stands in a three-quarter profile, hands folded on the hilt of a long sword planted upright. She has extremely long straight hair, strands falling past her knees; pale skin, elf-like pointed ears, narrow deep red eyes, and two smooth curved red horns on her forehead. Her expression is cold, detached, and slightly melancholic. She wears : the inner layer is a fitted white dress-style design with a deep neckline; a black sash and layered waist ornaments; over it, a semi-transparent patterned robe with subtle geometric motifs; the wide cuffs are lined with red, and the hem is decorated with smoky dark flame patterns. Her forearms are covered with polished silver armor, adding a warrior's aura. The giant sword is heavy and massive, planted vertically in front of her, the blade and hilt are black, with a metal guard, and vivid glowing red flame patterns flow down the center of the blade. The composition is elegant and balanced, blending traditional Japanese aesthetics with dark fantasy style. The background is a soft pale lavender-gray decorative collage, containing a circular window framing a view of Mount Fuji and a winding river, delicate floral silhouettes and blooming branches, abstract cloud patterns, hanging tassel ornaments, geometric fabric patterns, and a red sun ring on the right. The main color palette uses soft white, lilac, gray-purple, black, and deep red. Subtle paper texture, clean lines, soft cel shading, delicate highlights, and a gorgeous high-detail anime style are added. The overall atmosphere is serene, noble, mysterious, and slightly ominous, like the image of in a luxurious Japanese fantasy key visual.
