Edit image 1 (view from behind the two kids): keep the kids, suits, helmets, fins and the camera angle. Changes: 1) The giant jellyfish is almost invisible: the black water swallows it; only ONE oval patch of its matte dark wine-red surface shows where Yan's white helmet beam hits it, like a mysterious wall in the dark. The rest of the frame around it is pure black. 2) Far ahead, small blue flashes of light in the black. 3) Marine snow = tiny soft pale fluffy flakes, visible only inside the two beams. 4) Each helmet has exactly two side lamps. No text.
