Masked Idol Concert Portrait

Create a photorealistic close-up concert portrait of a glamorous male idol performer, framed from chest to head against a dark navy stage background filled with falling gold and white confetti. The performer has {argument name="hair color" default="platinum blond with subtle golden streaks"} shaggy layered hair and wears a white military-prince stage uniform with black and metallic gold trim, ornate epaulettes, star-shaped brooches, chains, pins, and sparkling embellishments over a black shirt and white tie. Add a white beret with black-and-gold decorative bands tilted on the head, dangling gold earrings, and rings on the hand. Pose him dramatically with one arm reaching toward the camera in strong foreground perspective, fingers slightly blurred from shallow depth of field, while the torso and costume remain crisp and luxurious. Place a large opaque beige square over the center of the face, completely obscuring facial features. Use high-fashion K-pop concert photography style, realistic lighting, glossy fabric highlights, cinematic shallow depth of field, celebratory atmosphere, vertical 4:5 composition.
