Hello Hentaibee,
I want to give a honest and straight answer what my opinion is.
Technically I can't say much about rendering in 3D.
I like fake and huge lips, butt and nipples.
I like fake and gigantic boobs.
I like prominent veins.
I like shapely nipples.
When I compare my tastes to this example, then
the boobs are a good size for me
the butt has a good size
the veins are a bit to extreme, I would love more skin colours you know that you have the
impression they rise the skin because of their size and a bit off darker colour.
the lips are too big
the nipples are too big and have no nice shape
Overall the girl is not appealing to me.
I liked your older renders better because the woman were more appealing to me.
