Not a fan of the decision to use two different art styles for the characters.
Some characters like Fiona, or Lyrana look much more anime like, compared to, for example Isabella or Scarlett, which look a bit more realistic.
Edit: I would even go so far to say it's three sligthly different art styles identifiable through eye size and how the nose looks.
Big Eyes: Violet, Pink, Ava, Elara, Fiona, Nura, Volupta, Gabriella, Lyrana
Medium Eyes: Blue, Diane, Juliet, Zephyra, Kaela, Lilo, Mara
Small Eyes: Isabella, Scarlett, Nyx
The big eyes ladies are the ones with the stereotypical small dot/line anime noses but Zephyra is a bit of an exception imho.
The rule seems to be: The bigger the eyes, the less pronounced the nose and the smaller the eyes, the more pronounced the nose.
Imho the medium sized eyes style looks the best but in the end I would prefer a consistent style no matter which eye size it is.
