Sorry buddy, if you don't see what's wrong there, either you're a bad sight, or have vulture eyes, they have much better eyesight than humans, maybe that's how you see all people in real life, or you just want to fool yourself.
The "human young skin" at naked eye, looks smooth and soft, the pores of the face are more visible, so I didn't put any pictures of the girls' faces, which show these textures especially on the cheeks, those images look normal.
You're only able to see that texture on the skin, when you use some augmentation, look at the comparison between the arm and the breasts, the breasts look wrinkled and the arms smooth. So something that should be very soft and smooth (female breasts) looks terribly bad.
the shoulders of the girl with the tattoo, looks like she has a burn scar.
Look at the guy's leg for God's sake, if your legs look like that, I recommend you see a doctor immediately.
The goosebumps in the buttocks, could work only if you reduce the scale of the texture.
My criticism is just that it's not necessary in the first place, it doesn't help and it looks bad. If the dev bought a hyper-realistic texture package, and received that, then he should demand a refund.
