Happy Tengu Samurai Concept Art

Create a full-body character concept illustration of a character name: a tall, lean, shirtless wandering samurai standing relaxed against a plain warm off-white background. He wears a vivid red tengu/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. Pose him in a casual contrapposto stance, one arm draped lazily over a long black sheathed katana or staff balanced horizontally across his shoulders, the weapon stretching far beyond both sides of his body; the right end has a black-and-gold diamond-wrapped handle and dangling tassel, the left end is a dark scabbard with subtle fittings. Dress him in tattered layered samurai clothing: a loose pale gray-blue haori slipping off one shoulder, dark green inner robe panels hanging raggedly, 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. Use angular painterly brushwork, high-fashion character design proportions, sharp cel-shaded planes, rough ink-like edges, visible fabric tears and folds, earthy muted colors with strong black accents, minimal ground shadow, and lots of negative space. No text, no border, no watermark.
