I'm so glad I was poked on my userpage about this. When you first submitted it I had no clue who this kid was... or even heard of the show back then. I'm a droolin fan of it now. And Aang's my favorite character. It's wonderful to see him in your style. I love his exaggerated proportions and the glow looks so good. I adore this.
By the way, when did you get your senior hat?! It looks good on ya!
