Potret Tinta Samurai Shinsengumi

Dramatic vertical portrait of a single Japanese samurai, inspired by late Edo period Shinsengumi aesthetic, standing front-facing in a dark mixed-media painterly composition. The subject is a stern adult male warrior with [messy black hair tied in a high topknot with loose strands], wearing a weathered [deep indigo blue] haori over layered black kimono robes and gray hakama. Shinsengumi-style white mountain-triangle (dandara) pattern around both sleeve cuffs, and a small circular mon crest on the chest. He carries two swords at his waist: one longer katana angled down to the left with a wrapped hilt, and one shorter wakizashi tucked near the center of the obi; his right hand grips near the sword at his side while his left hand hangs tense. Background features a large pale circular moon brush disk, a misty Japanese castle silhouette on the left, and a dark pine tree silhouette on the right. Bold black ink brush strokes, scattered ink splatters, rough beige parchment texture, and vertical accents of aged metallic gold leaf surround the figure. Dramatic chiaroscuro lighting, partially shadowed realistic face. Palette of black, charcoal, parchment beige, antique gold, indigo blue, and muted gray. In the bottom right corner, a small elegant signature block containing two text elements: "[May 31, 2026]" above "[Oyagi]" in cursive script. Vertical 2:3 poster composition, cinematic realism, no modern elements, no extra people.
