First-Person POV Dragon Rider Cinematic

Create a 30-second vertical 9:16, 24fps, 8K-quality photorealistic live-action fantasy sequence from a first-person rider POV. A massive original obsidian-crimson dragon with individually detailed scales, subtle dark mottling, molten-gold eyes, volcanic-black swept-back horns, blade-like dorsal fins, burgundy-red translucent wings and faint ember-like fissures across its body. Rider wears black leather gloves, dark-green sleeves and weathered leather bracers, holding heavy chain reins from a worn brown studded saddle. Begin with the dragon calmly breathing on a wet emerald coastal cliff; it slowly turns toward camera and the rider gently pets its neck. Suddenly it lowers its body, launches across the grass and leaps from the cliff. Dive steeply toward the grey-green ocean, deploy huge wings with realistic membrane movement, then skim just above the water with spray hitting the lens. Perform a dramatic high-speed bank around a sea stack, then plunge directly underwater. Brief dark-teal underwater silence with bubbles and faint crimson glow, followed by a powerful eruption through the ocean. Finish with a calm glide above foggy water as the dragon slowly turns and looks toward the rider. Use physically accurate anatomy, weight, gravity, wing aerodynamics, water physics, scale deformation, wind and environmental interaction. Natural rider-mounted camera movement, realistic motion blur, lens droplets, focus breathing, subtle handheld vibration, cinematic depth of field, soft overcast lighting, HDR, restrained film grain and natural cinematic color grading. Audio: atmospheric drone → intimate cello → rising orchestral tension → massive launch/flight score → intense percussion during the bank → muffled underwater audio → epic orchestral return during emergence → soft cello/piano ending. Layer detailed ASMR/SFX: dragon breathing, scales, leather, reins, claws scraping soil, wind, wingbeats, water spray, bubbles, ocean impact and a deep natural dragon roar. Make it indistinguishable from expensive real live-action cinema. No AI look, cartoon, anime, game CGI, plastic textures, fake physics, neon glow, oversaturation, distorted anatomy, extra limbs, text or watermark.
