An ultra-realistic cybernetic Japanese giant salamander rests on a rocky riverbed deep underwater in a dark, murky river.

Deep underwater at night in a small Japanese river. Very dark, low-visibility environment. The riverbed fills the lower half of the frame: smooth stones, silt, and sparse reeds. A cybernetic Japanese giant salamander rests directly on the riverbed, partially nestled between stones, completely grounded. No floating. No swimming. The salamander is still, with only minimal breathing-like motion. Cybernetic details are subtle and non-reflective, barely visible in the darkness, no glowing lights. Water is murky with slow drifting particles. Lighting is extremely dim, cold blue-green, as if moonlight barely penetrates the surface. Camera is static, low angle, medium-wide shot. Scene is empty, quiet, minimal, and sparse. No bubbles, no strong current, no extra movement. Mood is bleak, submerged, and contemplative. Ultra-realistic, cinematic, restrained. See more
