All three of my main girls have different body types (and one of them is even a princess, but it's a spoiler so I wont say who. It's not who you think it is.)
So there's Ravening...
Ravening is built like a bowling pin. Very light top, bottom heavy. I also tried to give each of them unique and unconventional facial features so she has a big round nose.
There's Ragna...
Ragna is a little rectangle of muscle and stubby limbs. Shes the polar opposite of the typical super leggy/thin anime girl and was inspired by how female gymnasts are commonly built. She also has massive ears and an upturned nose.
and finally Randy...
Randy is a tall gangly beanpole. She has the opposite build of Ragna. As the magic user of the three she also has next to no muscle. Randy's facial features are all from her being a fish-girl (no nose, big shiny black eyes, fin ears).
My goal was not to look at any of this as physical flaws, but traits that make them unique. Also its just good character design to have recognizable silhouettes, which was also important to me.
