Requesting her stomach to be shopped into @nataliaacevedo62's, please.
A sort of slim, yet still fit sort of look with plenty of emphasis on the tummy and V-line as shown in the references below.
Mainly just hoping for you to crop the video stomach onto her with changes to make it suit her better, although if you look up her username, there's plenty of good material.
I've attached some videos here you could rip from:

Also feel free to redo the hips and waist ratio on her if that's easier too, so long as she has wide hips and a thin waist.
