Gonna throw in my two cents cause why not.
I kind of associate the "acting" of the character in my headcanon with their looks a lot, so changing looks always comes at a detriment to that headcanon (and lots of people go REEEE at that, but you probably knew that).
What makes this change particularly "difficult" for me to get used to is that I personally associate the new hairstyle with a different character in terms of behavior.
Sure, how the dialogue is written can compensate for that, but with Alice I don't have that issue at all. Maybe because how much face is shown and the portion shown does not change much for her, but for Kana it does
Also: Sudden surprise
It makes Kana's face look strangely unfamiliar despite nothing else changing compared to the other "After" image.
