I am absolutely obsessed with the fact that Korra cut her hair, I think it really represents a completely new perspective that we're going to see in the new season as well as her growing up. < it looks like my hair :)
The cover art from The Legend of Korra: The Art of the Animated Series- Book Three: Change. I loved everything about this season. The artwork for the air temple paintings took my breath away (like Zaheer did the Earth Queen).
