Edit image 1 (character turnaround model sheet). Keep everything: the layout, the shared floor line and scale, the height ruler, labels, the faces, hair, braids inside the helmet, suits, fins, proportions and render quality. Change only the equipment so it matches the original series design shown in images 2 and 3:
HELMET LAMPS: on each helmet, on the left side and on the right side at ear height, a dark-grey round puck-shaped lamp housing is mounted on the outside of the glass bubble, like the cup of a headphone. The front edge of each puck carries a glowing white lens: from the front it reads as a bright white vertical oval strip at each side of the bubble; from the side the whole round dark-grey puck is visible with its glowing front edge; from the back only the dark-grey back of each puck is visible. Exactly two pucks per helmet, the same on Kira and Yan in all eight views. The rest of the bubble is plain clear glass; a glowing white ring at the neck, with a short coloured light under it: violet for Kira, cyan for Yan.
BACKPACKS: a rounded black backpack with a curved glowing light arc near its bottom edge, violet for Kira, cyan for Yan, as in image 2.
WATCHES on the LEFT wrist: Kira wears a wide light-grey band with a small orange light, as in image 3; Yan a dark rectangular watch.
