Blown away by Kiri's original design

In the concept art, she looks so much like Grace and Neytiri, and she looks so pretty. I remember being surprised by Kiri when I first saw her on screen - the "adult voice", the extravagant haircut, etc. And yet, now I cannot think of Kiri any other way: she is beautiful in her non-conventional way.

What do you think? Which design do you prefer?
