I don't think any of the LIs are ugly. But I do think that the story tries a bit too hard to make them look uniquely different from each other. Whether it be their eye color or other features. At least when it comes to the children and MC with his siblings.
Take Katie, for example. While obviously it's possible for her to inherit her looks from her grandmother. As stated in the game. There's no resemblance to her siblings or her parents at all. She looks like she's Lilith's child and probably should've been. Since their behavior are shown to be damn near the same. Except for their taste in colors.
Then there's MC. We know his mother is a redhead and his father is blond. So why does he have black or dark brown hair while his siblings have red and blonde? Again, not that it's impossible. Just a bit weird. And don't get me wrong. Diverse looks are fine. But in this case, it seems a bit heavyhanded.
I'm not asking the devs to change anyone or anything with this post, by the way. Just stating my extremely minor critique. As I said already. The LIs look fine.
