คอนเซปต์อาร์ตซามูไรพเนจรหน้ากากเท็งงุ

Full-body character concept illustration of a [Happy Samurai]: a tall, lean, shirtless wandering samurai standing in a relaxed contrapposto stance against a plain warm off-white background. He wears a vivid red tengu or oni-style mask with an extremely long pointed nose, two tall horns, dark expressive eye openings, and a wide laughing open mouth, giving him a mischievous happy expression. Small purple flowers are tucked near the mask and hair. One arm is draped lazily over an extra-long black sheathed katana balanced horizontally across his shoulders, extending far beyond both sides of his body, featuring a black-and-gold diamond-wrapped hilt with a tassel. He wears tattered, layered samurai clothing: a loose pale gray-blue haori slipping off one shoulder, ragged dark green inner robe panels, oversized dark blue hakama pants cropped above the ankles, a thick tan rope belt tied in a large knot at the waist, and straw rope sandals on bare feet. Rendered in angular painterly brushwork with high-fashion character design proportions, sharp cel-shaded planes, rough ink-like edges, earthy muted colors with strong black accents, minimal ground shadow, and generous negative space. No text, no border, no watermark.
