Underwater Sci-Fi Combat Scene

Prompt

15s, 16:9, ultra-realistic underwater sci-fi action film, cinematic live-action VFX, deep blue murky ocean ruins, floating particles, bubbles, volumetric light shafts, broken metal beams, giant circular submerged structure, no text, no watermark, no cartoon, no game UI. Character lock: Use Image 1 as the only reference for Alin. Keep her exact face, long pale blonde hair, silver-black female biomechanical armor, orange glowing details, sleek full-body combat suit, realistic metal joints, strong feminine silhouette. She is a high-tech underwater combat pilot, not a normal diver. Monster lock: Use Image 2 as the only sea monster reference. Keep the exact prehistoric aquatic predator design: long narrow crocodilian skull, huge mouth, dense sharp teeth, dark wet skin, heavy neck, four flippers, long tail, realistic marine reptile body. No tentacles, no octopus creature, no abstract shadow monster. Rhythm: Fast entry -> brief lock-on -> sudden predator pass -> near-death dodge -> close-range counterattack -> dark suspense ending. 0.0-1.5s Fast forward dive into the underwater ruins. Alin rushes through bubbles and broken beams with blue thruster trails, entering the core of a giant submerged structure. 1.5-3.8s She brakes and stabilizes in front of a huge circular ruin opening. Her forearm armor unfolds into two glowing blue energy blades. She senses something nearby. 3.8-6.0s A massive shadow of the monster suddenly cuts behind her at high speed. The water current slams her sideways. Only parts of the head, back, and tail are clearly seen as it rushes past. 6.0-8.2s Hard danger beat. The monster lunges with jaws wide open. Alin drops and twists beneath its mouth and front flipper at the last second, slicing a short blue energy scar across its neck as she escapes. 8.2-11.5s She flips back into control, thrusters fire, arms cross to charge, chest and forearms flare bright. She delivers one brutal close-range blue-white pulse slash into the monster, blasting bubbles, silt, and debris outward. 11.5-13.6s The monster is driven back into the darkness of the ruin, not killed, only forced away. Alin holds position with both blades still active, ready for the next attack. 13.6-15.0s Final suspense shot. Camera slowly pulls back. Alin floats in the foreground with her back to camera. In the deep darkness behind her, the monster’s head and teeth slowly reappear, signaling round two is about to begin. Lighting: Cold deep-sea blue, high contrast, realistic underwater scattering, sharp blue energy flashes, faint orange armor glow, dark abyss pressure. Sound: Deep water rumble, bubbles, thruster whine, armor deployment clicks, monster water displacement, heavy underwater bite impact, sharp energy charge, muffled shockwave. Negative: No tentacles, no extra creatures, no blood gore, no one-shot kill, no bright fantasy colors, no stiff floating pose, no distorted anatomy.
