Edit image 1 (character turnaround model sheet). Keep the faces, hair, suits, colours, watches, backpacks, fins, the single oval helmet lamps and the render quality. Corrections:
1) ONE SHARED SCALE: put all eight figures on ONE common floor line in a single row order (Kira FRONT, 3/4, SIDE, BACK on the left half, Yan FRONT, 3/4, SIDE, BACK on the right half), drawn at the same scale, so Kira (127 cm) is clearly shorter than Yan (157 cm): the top of Kira's hair reaches Yan's chin. One height ruler at the left with marks at 127 cm and 157 cm at the top of each child's head (hair, not helmet). Labels FRONT, 3/4, SIDE, BACK under each figure.
2) SIDE VIEWS: the visible lamp sits on the side of the bubble right over the temple, just above and slightly in front of the ear, at the middle of the bubble's side, exactly where it is in the front views; the back of the bubble is plain clear glass with soft neutral reflections only.
3) Kira's two braids lie fully INSIDE the glass bubble, curving over her shoulders inside the helmet; the glowing neck ring is closed and nothing passes through it.
4) PROPORTIONS: slightly smaller heads: Kira about 6 heads tall, Yan about 7 heads tall with broader shoulders and a longer torso, a believable lanky 13-year-old; same soft stylized 3D look.
