That is pretty much like most of the girls I was with in the mid 80's through the mid 90's. By the late 90's, most of them were either completely bald or just had a landing strip. I only had one that was near Demi territory and she was one of the only ones I did not go down on as part of foreplay.
My line is when it has grown out to the thighs, she should still be able to wear a normal bikini without showing hair (or getting an indecent exposure citation in many places). Up the crack of the ass is a bit much as well. But a decent triangle and on the labia, that's not a problem, and feels nice to play with during foreplay. I don't mind shaving the labia - can take it or leave it - but I want something up front, and long enough to play with.
Straight up Barbie doll bald is, quite frankly, boring. Unless she's got her legs wide open there is not much to see on most women if they don't have hair. Could be looking at anywhere else on their belly for all the difference it makes.
But it is simply fashion, over the centuries it has swung back and forth - although it was usually only the wealthy that could afford to worry about that level of grooming in the old days. Now it is little different than how you style the hair on your head, just another fashion choice for people to follow because it is the "In Thing". And the pendulum is swinging the other way, that while the majority of women do groom, fewer are going for completely bald.
and what it this ? poor future-toddler will suffocate.....
This is something I have noticed a lot, that scaling up the boobs on some models seems to result in nipples the size of small coke cans, which are not of much use to anyone. Not being familiar with 3D modeling I am unsure why this is, but I notice it with many large breasted models in games.
Thing is.. while nipples do vary in size, it isn't by that much because they have a function, and will be of no use if too big. The areola can be quite big on large breasts (sometimes even smaller ones), and after giving birth many women will find the areola and nipples have grown in size, but the nipples don't get as absurdly large as you see in some games (and bad art).
After a quick internet search this young woman has what seems to be the upper range of nipple size you'll see without finding someone with a deformity.

Her breasts are bigger than the CG image above, but her nipples are maybe half the diameter, or less. They also don't look like they came off the end of a large novelty pencil.
I've also noticed that even black models in these games have pink anuses and labia.
The labia majora and the anus is typically the same shade as the rest of the woman's skin. Even the labia minora are typically dark - often a darker shade similar to their nipples. Only the inner vulva from the clitoris to the vagina is pink.
I don't know if no one makes genital models for dark skinned women, or the modelers are just lazy, or what, but it doesn't make for good game art, whatever is the case.
