Edit image 1: keep Kira on the LEFT and Yan on the RIGHT, their faces, suits and poses. Changes: each helmet has exactly two side lamps, their white beams point toward the jellyfish. The jellyfish has exactly FOUR broad flat ribbon arms trailing down several metres; its matte dark wine-red body is visible only where the beams touch it, the rest fades into pure black water. Marine snow = tiny soft pale fluffy flakes only inside the beams. Kira wears a round watch on her LEFT wrist, Yan a rectangular watch on his LEFT wrist. No text.
