It was examples for unrealistic drawings, not yours specifically. If you do not draw realistic looking (most do not), you make artistic choices how far you stray from reality, or rather in what way. Resulting in a style.
Your style is fantastic.
But the hyper extreme sizes are not a style choice. It is not how you draw, it is what you draw. You realistically draw those absurdly large assets. And that takes a step further in suspension of disbelief. I already have the layers of this being a game, fiction, and of course the demon stuff. Nothing in this frame work allows for boob size bigger than a person, hence the need for a further step .
Iirc correctly we see the first woman behind a door, hiding her size. Then he makes his deal.
He wakes up, we see the size of the woman and he only thinks, how hot she looks. But the absurdly large sizes are apparantly normal to him.
For his absurdly large size there is an ingame explanation, so I wondered, if there maybe is an ingame explanation for the women's sizes as well. From the introduction it almost seems like either many women were altered or at least look to him like that, so he knows who the 30 women are.
