Someone on reddit asked how Korone is "so pretty" (their words, not mine!) even though she's a dunmer and, first off, there are plenty of extremely attractive dunmer in TES? I don't know what that's about. With regard to player characters, I think people are just impatient. Like, no, her model doesn't look exactly how I draw her, but she's pretty close.
I play on PS5, there are no mods involved to make her look like this. If I did have mods, I'd only modify colors a bit? I'd like to plug in a custom texture for her eyes to make her sclera the right color—I couldn't pass up the irises in that eye type, but in my head her sclera is the same dark red as the rest of her race—and fix the issue where black hair doesn't actually show as black on player characters, because her hair is supposed to gradiate from silver to black.
I don't have her sliders saved, and I wouldn't share them even if I did, but she's literally "just" the result of over an hour in the character creator. I think everyone insisting that Oblivion Remastered doesn't allow players to to make good-looking characters should spend a year learning to make them in vanilla Sims 4.
EDIT TO ADD: Also, to be completely clear, I think Korone looks good primarily because the goal in designing her was not to make The Most Beautiful Woman In The World, but rather to create someone who I found attractive and looked like a person. She doesn't have the smoothest complexion option, her face is more lined than a lot of people would opt for when trying to make a "pretty" character, but the fact of the matter is that hallmarks of youth are not factors in attractiveness. She would not look as good as she does if I went with those options, because she'd look more artificial, and that's a big part of why characters don't look "good." The key is to make a character who looks like a person, and to take your time doing it.
