It's pretty but it's unusual to see Korra not her natural skin color. Sure she looks pretty this way (and in her normal form<3). BUT, we live in a society were lighter skin is the ideal image of beauty. For the most part this will send out a negative message now matter how pretty it is. And it is pretty. I just hope you know and watch what your doing so nothing goes wrong.
Wow this is whitewashed pretty badly. It could stand to be corrcted? Considering this is one of the most popular pieces on the Korra tag, it sends a pretty bad message about what is favored and what is not. I realize you made this before Korra's official appearance was released, but the contrast between what actually is and what is represented here is striking.
There's really no reason to get nasty, first of all. Secondly, while she might have been paler in concept art, in the actual show you can see that she is brown. I was simply trying to point that out for references for future artwork.
