端正な男性キャラクター

Create an original handsome fictional adult man, age 30, as an anime-style 3D character illustration for {{service}}. Give him {{appearance}}, adult proportions, a composed expression and a subtle natural smile. Dress him in {{outfit}} with {{palette}} colors. Show a relaxed standing pose in three-quarter view, one hand resting loosely at his side and the other holding a closed unbranded notebook. Refined cel shading, soft key light, delicate rim light, clean material separation and a memorable silhouette. Full body visible from hair to shoes, with generous margins on a plain warm-gray background. No text, logos, game interface, watermark or duplicated accessories.
