Personally, I don't really see the issue, I guess. I feel like Zoe's current model looks great. I look at her and I see Zoe. So it's hard for me to understand how other people look at her and see some sort of doppelganger. Not to dismiss the argument, I understand that people have some really strong opinions on the topic. I just don't see it. I feel like her current model looks much closer to "old" Zoe than the original pre-alpha model, while still updating her look to take advantage the new technology the team has access to.
As far as her hair... Personally, I think her hair looks good, but I'm a little disappointed to not see her rocking one of the "wilder" hair style options we were presented with. We know that there will be a degree of customization allowed for her outfits and I believe there was some mild implication at one point that there may be more than one hairstyle in the game?
From the original FB post:
Our graphic designer Christoffer Grav is currently working on ideas for the various hairstyles our heroine will sport during the course of the game.
That to me says that her hair may change. Whether that's something that happens on its own or if it's something that we can do through the character customization, I don't know. But I wouldn't be surprised if we can tweak it a bit. Or if maybe backers of a certain tier can. Or however the heck all of that shakes out. Time will tell.
