The first form of Emiko (the one used in the main menu) is clearly the same model as Chloe from A Mother's Love (which I -contrary to popular opinion - think is cute).
Obviously for day 3 you already put some effort in making her your own (so much so that I wouldn't have seen the similarity if I hadn't seen the main menu) and I like her this way.
And while this rework is more beautiful than the current day3 form to me she looks too realistic in comparion to the other ladies.
So, while this is her most beautiful form imho, I think she'd be a break in style if she's the only one receiving that treatment.
EDIT:
Okay, with this side by side comparison, just go for the new one!
The color of her skin is a massive improvement, looks way healthier!
EDIT2:
Overall I gotta say that it's astonishing to see the level of improvement over just the last two months, kudos, mate!
