Cinematic Biker Powder Explosion

Create a vertical 9:16 cinematic 35mm action portrait of {argument name="character name" default="a powerful male biker"} riding a modern black street motorcycle directly toward the camera inside a dark industrial tunnel. The rider is centered and symmetrical, leaning forward aggressively with intense posture, both gloved hands gripping the handlebars, wearing a fitted black racing jacket with small motorsport patches, black pants, protective gloves, and two gold chain necklaces. His hair is short, dark, and slicked back; place a smooth rectangular blurred face area over the face as if anonymized. The motorcycle has a large glowing round headlight, amber side indicators, thick front tire, visible front forks, glossy black fender, and sharp realistic mechanical detail. Behind him, create one enormous explosion of colored powder made of exactly four dominant color clouds: bright cyan-blue on the left, vivid red across the center-left and right, hot yellow on the right, and small pink/magenta accents mixed near the top center. Add orange flames wrapping around both sides of the front wheel and lower motorcycle, with sparks and embers. Use strong tunnel motion blur radiating backward, teal-green fluorescent lights along both tunnel walls, wet reflective road streaks, dramatic contrast, shallow depth of field, high-speed energy, ultra-detailed photorealism, cinematic teal-and-orange grading, low front camera angle, no extra vehicles, no readable text, no watermark.
