가죽 재킷과 청바지를 입고 당당히 서 있는 자신감 있는 젊은 남성

a full body young man with a striking, masculine appearance and a confident, composed expression. His face is rendered with extreme precision — sharp jawline, high cheekbones, and subtly parted lips. His skin tone is fair with smooth texture and natural highlights emphasizing bone structure. His eyes are vivid blue-gray, reflecting light with crystalline clarity and a faint glint of intensity. His gaze is direct and piercing, framed by dark, thick eyebrows that add definition and character. His hair is dark brown, wavy, and slightly tousled, with individual strands catching soft light; the texture should appear rich and natural, showing volume and movement. His physique is athletic and well-defined — visible muscle contours along his neck, shoulders, and chest beneath his clothing. The lighting should accentuate the subtle tension in his posture, revealing the sculpted lines of his upper body. He wears a black leather biker jacket with silver zippers and buttons, layered over a white dress shirt that is partially unbuttoned at the top. The leather should appear glossy and textured, with creases and reflections that convey realism and tactile depth. The shirt fabric should contrast with the jacket — crisp, slightly rumpled, and soft under the light. He also wears light blue denim jeans with a slim fit, showing natural folds and fading around the thighs and knees.
