It's also really fun how in the picture, Katara and Aang are younger than the kids. It makes me think about generations and comparing the Aang and Katara we saw in Avatar to the ones who are referenced (and sometimes seen) in Korra. Awesome picture!!!
Gotta love the cloud babies. Stratus, Cirrus and especially Cumulonimbus. He's my favorite (ironically, considering I have a fear of cumulonimbus clouds because they can produce that most violent of windstorms, the tornado).
