Besides these 3 girls having slightly different designs and builds, there is another point in the panels I could talk about.
The characters interact. They don't just line up all parallel to each other.
They move in and out of each other's spaces. They react to each other's movements.
They are all acting independently. When doing this, you have to be careful to still make their different poses add up to a clear overall composition, so it doesn't look chaotic.
Even their legs move independently.
And they have knees made of both flesh and bone, not just cartoonskin.
