To be honest, I'm not fond of her hair. I wonder if someone can mod a Mohawk for Sera.
*don't hurt me*
I'm not really into her hair, either. Kinda like how I wasn't into Leliana's
Origins face, or Isabela's piercing, or Liara's freckles.
Voice and personality are more important to me. If there's something I don't like about a character's features, I just learn to deal, or work around it, because changing those features feels dishonest and a mutation of the way the character was designed. Not as bad as a whitewash, but still...unsettling.
The only exception I make to this is Leliana's face, which looks nothing like the art or trailers from pre-launch, and which, I am convinced, is purely an art screwup. The nose...and the sunken eyes...and the potato face...aaaaagh.
Sera's hair is kinda gross, yeah, but it's also supposed to tie into her personality, and I'm totally okay with that.
