Like I keep saying, with regards to each girl's muscle growth, make their body type diverse. So it's cool that for Stella you're going for the bulky wide powerlifter build. Jade should probably be the more leaner shredded build for MMA and speed, like a sleeper build and Aline should ideally be somewhere in the middle of those two like a crossfit build. I think googling various female body musculature as it pertains to different sports: MMA, crossfit, bodybuilding, kickboxing, powerlifting, weightlifting can help you get an idea of the diverse body types you should go for with each girl. I still very much want this to be a thing so I keep reminding you of it.
Here is a great frame of reference. It's a korean webtoon comic called Muscle Gurl's Colleseum. It is still in korean, but every girl you see is super muscular but very different body types: https://novelpia.com/comic_episode/905
I think with Jade you should either go for the Chinese Girl in Chapter 2 or the Dark haired girl in chapter 1. The Lean MMA body type.
