oh my god, what are they doing? O____o Are they playing strip-Pai Sho? I think Katara will lose... You cannot win against an airbender, against Aang! (=_____= ok, it is very late for me...)

however... Kataang! ^///////^ simple but sweet, I think (and I hope).. I do not like things too explicit (not always xP) and I wanted to draw a moment really special for Aang and Katara. Are they married? If you want it =3 I was very happy when, in a news about "Legend of Korra" I knew they had a son, Tenzin. ( in this sketch, below, I wrote "Tenzin in progress". how stupid!)
Take that Zutara! Kataang 4ever!
EDIT: I added a shadow beneath them, so it don't seem that they're floating in the void.
