Nice looking Pastel, I prefer a lot of blushing like that girl.
As for Browning, from what I can see in that picture there will be more browning with age. See everything that doesn't look like clean yellow that is usually what turns brown with age. How dark or light the brown will be will just have to wait and see. She is still young and the browning will progress with age. She is still a pretty pastel, and in my opinion will probably still be nice looking adult (I think Some Brown adults are pretty depending on the shades of brown and the blushing).
Price: I would guess in the $250 - $300 range currently
