Delicious tea, or deadly poison?

Woah, I think I want to marry the artist who made these sketches of possible grown-up looks for all of the Avatar characters. I mean...guh...Wow. Um, I know one's not supposed to have mad crushes on animated characters but bad boy adult Zuko is HAWT.

Apparently it's by Isaia, whose Deviant Art page I must now bookmark.

This is really, really making me want to start drawing again, oh yes it is. Move first, draw later.
