This is kind of like an upcoming scene in my fan fiction, where Katara and Zuko date on Ember Island and try to make the most of their time before Sozin's Comet. … Your artwork is really good, well done.
Oh neat! Also, I just realized how many of my zutara drawings take place in season three (a lot). But thanks (: Feel free to use it for your fic if you want it as a cover photo or reference or anything.
