Middle-aged man singing on stage, guitar, Hanfu, Rembrandt light AI Image Prompt

A middle-aged man in his forties or fifties, standing in three-quarter profile on a stage surrounded by an audience, a guitar hanging from his neck, playing the guitar and singing into the microphone, head slightly bowed, weather-beaten with a hint of sadness, stubbornness, and detachment, kind-eyed, high-bridged nose, slight stubble. A man with stories, focused and interesting, singing about life's insights and defiance, voice low and slightly hoarse, clear and resonant, with precise rhythm and unwavering gaze. Dim lighting, cool-toned atmospheric light highlighting the portrait, background blurred into cheering audience, angular square jaw with grayish stubble, high nose bridge cutting light and shadow, crow's feet at the corners of the eyes coexisting with vertical frown lines between brows, thick palm gripping a wireless microphone, eyelashes casting shadows when bowing head to sing, eyes shining brightly when lifting gaze. Inner white crew-neck shirt, outer black traditional Hanfu open-front jacket, all buttons undone, cotton knot buttons. A face where world-weariness and youthful spirit contradictorily blend, a calm smile at the corner of the mouth carrying an unyielding stubbornness, neck veins bulging with raspy high notes. Realistic thick painting style, light and shadow referencing Rembrandt triangle lighting, color palette using navy blue/warm orange/silver gray contrast, adding vintage soft focus filter and vinyl texture overlay effect, close-up, I'm about to sing.
