Looking for a semi realistic picrew creator for book OCs?

So, I'm in the process of planning and writing a queer "fantasy-esque" book. The characters in my book are all humans though. I'm at this point where I want to be able to visualize some of them, but I definitely want to stay away from AI. Also: I'm decent at drawing, but suck at proportions and drawing people. That's why I came to picrew. I won't use the picrew pics for covers or in the book itself. I just want to have an understanding of what a character looks and feels like — especially if and when the book is ready and I want to commission an artist for a proper cover.

With semi realistic picrew creator I mean: I want some decent shading and semi realistic proportions. What I don't want: anime and Manga styles (have nothing against those, it's just not what would help me visualize my characters the way I want to).

If some of you could help me find a creator which could help me, it'd be greatly appreciated. I looked through picrew already, but I do struggle to navigate a bit. And the amount of creators is astonishing, albeit a bit overwhelming.

Thanks in advance xx
