It's official: you have reached a whole new level of awesome: OMFGAWESOME! What do I like about this? Lets start with the subtle layer over the top. It adds rich texture and depth. The color choice is striking. Aangs expression, clothing, and pose are all perfect, and even the little details, like the tiny pieces of his glider that are flying off in the wind (how DO you come up with stuff like that?!).
Yay, new stuff! Season 3 looks good, I've only watched a couple episodes from seasons 1 and 2, but I'm gonna watch 3! The shades of colour used really bring out the mood, and I like how you drew Aang's glider.
