I'd like the Quarian to be like Tali's photo. Maybe not with long flowing hair? I was both expecting hair to be human-centric (so no other races have to suffer from BioWare obscene hair) or to be short or braided?
What I found depressing was that it was a photoshopped photo. Not even a real portrait. There wasn't even some study on Tali's face, she was an afterthought if there was one.
I really hope the team this time will cure a little more the Quarian and give them a real face.
Well, I think they nailed the long flowing hair if you look at the fabric at the back of Tali's head (hood) for example, you'll notice a baggy section that looks exactly like it would if they had long flowing hair bundled into that fabric.
I'm hoping for a little more...uniqueness out of the Quarian appearance.
If you look at the turians, drell, Salarians and on and on they all have a unique appearance. And so should the quarians IMO.
