I don't want to tell you how to write your story, but I am very interested in twothings. I would absolutely love to see Luca actually gain the emotional strength to take on Blair, and I so desparately want to see Blair humanized in some way. I think it would be very intersting if Daisy actually died (likely by suicide because Blair is very careful to not kill her) and now Blair has to face the fact that she did that. She straight up drove an orphan to suicide for her pleasure. What I want more than anything is for entitled people like Blair to realise the permanence of their actions. 

I love the giantess content, and all of the humiliation and domination and such. It is quite a story like no other, and what I'm about to say is independent of the fact that this is beautifully written and interesting to read.

I'll focus on Leah for now. To put it simply, she's the weakest of all the characters (yes, including Annabel). Why? Simple. She believes herself superior to others because of her genes (I don't think I need to spell out exactly what kind of regimes Leah might support). However, the only people she ever excersises her "superiority" over are those who cannot fight back. That's weakness in my book. If she's so superior just by her genes, why does she need the help of a machine to assert said superiority? Can she or can she not win a fight against a person with HDD who has not shrunken? My guess is no. And she knows she can't. Maybe she does know she's a small, small person who tries their best to act as if an end won't come to her just as mercilessly as it came for so many that she's killed. And thus, she knows nothing. No matter how many she kills, she can't change the fact that she is only human, and a single human is no more than a blip on the earth. Leah's death won't be felt any more than Annabel's, and to pretend so is a fool's way of convincing herself superior. The fact that she is rich and has no consequences for her actions plays into it, but everyone knows how little spoiled rich kids contribute to the world. Leah's character is layed out already. She thinks herself more than human. She thinks that all of those murders will help her. And whether there's an afterlife or not, there is still no hope for Leah. She remains less than each individual she thinks herself superior to.

Harper, Molly, and Naomi haven't been layed out as clear, and as far as I can tell they're just apathetic and selfish, and just take Leah's word because it means they dont have to work to better themselves at all. But we'll see what kind pf people they turn out to be. But one thing's for sure. I won't be shedding any tears if the world lost those four.
