Tattooed Anime Man in Marble Hall Prompt

Create a highly detailed anime-style portrait of a beautiful androgynous young man named {argument name="character name" default="Smar"}, shown from upper thighs to head in a bright white neoclassical hall with tall marble columns, ornate arches, soft sunlight, and a pale luxury atmosphere. He has {argument name="hair color" default="messy black hair with subtle ash highlights"}, long tousled bangs partially covering one eye, pale skin, a slim but muscular defined torso, sharp collarbones, narrow waist, and a calm alluring expression with slightly parted lips and gray-blue eyes. Dress him in an open black sleeveless hooded zip jacket hanging loose off the shoulders and unzipped to fully reveal the chest and abs, paired with loose black drawstring athletic pants; his hands are tucked casually into the pants pockets. Add intricate black tattoo work as the main visual feature: full floral lace-like tattoo sleeves covering both arms and hands, ornamental black tattoos rising from the lower abdomen and hips, side-rib tattoos, and a dark botanical tattoo climbing the side of the neck. Include a thin silver chain necklace with a long cross pendant and small dangling earrings. Use a refined semi-realistic Japanese illustration style with delicate linework, glossy soft shading, dramatic fashion-editorial posing, high detail on skin, fabric folds, tattoos, jewelry, and hair strands. Composition should be vertical 3:4, centered figure, softly blurred architectural background, white and charcoal color palette, gentle backlighting, elegant sensual mood, no explicit nudity, no extra characters. Optionally place a small white handwritten signature reading {argument name="signature text" default="Smar"} near the right side of the upper torso area.
