Id like to see the flat, yes. If that was naatiri (however its spelled) She has a mannish jaw. The naavi hair was long, so id make it go all the way out and hide the neck.
It's lookin' all great, however I think it's too realistic. I think the problem is, here, that the well made texture just looks very goofy on a round sphere, on a 3d model of a navi it would look fine, but on this, not really.
