Still very much a work in progress, but I wanted to share some updated character comparison sheets for Echelon-7.

Images 1–3: Characters grouped by height, tallest to shortest within each image. All are shown in the same lighting, pose, and outfit so the focus is purely on body proportions, height, and overall silhouette.
Image 1: Liora, Kendal, Serra-9 (pre-cyborg), Savannah, Mia
Image 2: Nyssa, Mara, Sloane, Isabella, Val
Image 3: Amelia, Lyra, Emily, Hana, Rina

Image 4: A cross-section of the height range to better show the differences across the cast.
Left to right: Liora (5'11"), Mia (5'7"), Sloane (5'6"), Lyra (5'3"), and Rina (5'1").
The goal is for each character to have a recognizable silhouette and body language, even before clothing, expressions, or hairstyles are added.
