Anime movie film still, cinematic anime, high-budget animation. Wide shot of a young woman in a small glass-domed submersible descending through dark ocean depths, her face illuminated by the green glow of the cockpit instruments, both hands pressed against the glass dome as she stares upward in awe. Her short dark blue hair floats slightly in the cabin. Outside the glass, an enormous ancient sea creature — a whale-like leviathan covered in bioluminescent blue markings — glides directly overhead, so massive that only a portion of its body fills the frame. The creature's bioluminescent patterns cast a rippling cool blue light across the submersible, the woman's face, and the surrounding dark water. Tiny glowing deep-sea particles drift between them like underwater stars. Insignificance before something ancient and beautiful. Deep ocean black, bioluminescent blue, cockpit instrument green, dark blue hair, particle glow. Extreme scale contrast — tiny sub, colossal creature.
