Piece 2, frame 5. Redraw image 1 as a new 16:9 film frame, keeping its camera and composition: the two children floating side by side, Kira (small) LEFT of centre and Yan (taller) on the RIGHT, a giant jellyfish bell filling the left part of the frame next to them. Change the jellyfish and the light:
The jellyfish is a giant Stygiomedusa: a matte, dark WINE-RED rounded bell about one metre tall, exactly as tall as Kira, with EXACTLY FOUR broad flat ribbon arms hanging down and trailing away for many metres into the dark. It does NOT glow; it is dark and velvety, seen only in the patches where the children's white helmet beams touch it. No other jellyfish in the background.
Design of the children from image 2 (character card): clear bubble helmets with exactly two dark puck lamps outside the glass, white capsule lights on the front, beams going forward onto the jellyfish; neck rings violet (Kira) and cyan (Yan); orange suits; one watch each on the LEFT wrist. Pitch-black water at 4000 m, fine dust only inside the beams.
