Night Sea: Mech Guardian Protecting Fishermen AI Image Prompt

Late night sea, extreme low angle upward shot, camera at the deck height of a fishing boat, 24mm ultra-wide angle, film grain, dark tone with teal-blue cold cast. A worn wooden fishing boat sits in the lower left corner of the frame, mottled wood, fishing nets and buckets scattered on deck, a dim yellow kerosene lamp swaying slightly at the stern—the only warm color in the scene. Three or four fishermen huddle by the gunwale, looking up at the sky, their silhouettes tiny. A sea monster bursts out of the water about forty meters in front of the fishing boat. Its body is deep gray-black, covered with barnacles and bony ridges, jaws wide open, fragments of torn fishing nets hanging between fangs. Below the waist, it dissolves into waves and dense fog, you cannot see its full form. A giant mech guardian stands between the fishing boat and the sea monster, side-facing camera. The mech is about fifty meters tall, with dark blue rusted armor plates welded together, surface covered with battle scratches and seawater erosion marks, exposed corroded hydraulic rods and cables at joints. The head is angular, eyes emit cold blue focused light, a row of small indicator lights on the side of the head glow dark red. The left arm stretches across the middle-upper part of the frame blocking the direction of the sea monster, forearm armor flipped outward exposing internal metal skeleton; right arm extends slightly toward the fishing boat with a half-open hand, as if protecting something. The cockpit area on the chest emits warm orange light, shoulder heat sinks emit white steam blending with sea mist. A diamond-shaped energy core in the center of the chest pulses with blue light. Light source comes from a lighthouse on a reef far right, sweeping fan-shaped white-green beams. The cold light sweeps across the mech's armor creating cold metallic rim light, leaving contour light on the sea monster's bony ridges, and the fishing boat is illuminated only for an instant as the beam passes. Deep teal-black seawater, dense fog engulfs the mech below the waist, the distance completely fades into darkness.
