"A man with short hair and a stubble beard wears dark-framed glasses and a light-colored jacket over a white turtleneck. He has a thoughtful expression, looking slightly to the side. The background is a solid, muted green, creating a clean and minimalistic setting. The lighting is soft, evenly illuminating his face and clothing. The composition is a close-up portrait from a slightly low angle, focusing on his upper body and head, conveying a calm and introspective mood."
