Avatar martial arts sketches

Due to creating artwork for my classes all the time, I rarely get time to do any free doodling or merely have any energy to want to. So this afternoon I sat down, watched some Avatar episodes and drew some element-bending studies. They're basically gesture drawings (although the air bender has Aang's head tattoo), but I figured they may be interesting enough to share.
