Movement

For my final project I want a character to summon the four elements, and so I need to consider how he will move. I would like him to be levitating, so I need to consider how he moves through the air.
The last Airbender also tackles a similar challenge:

This is a link to the trailer on YouTube. In the last Airbender, the characters "bend" the elements through martial arts. What I liked about this film was that their motions reflected the element that they were "bending".
Keeping that in mind (their motions reflect the element they are bending), I would like to do something similar.
Inspirations that I can draw from are: martial arts, swimming, gymnastics, and ballet.

I want fire to be direct and sudden like it's being fired from a gun. With the water, I want the character's motion to look like he's moving through water (similar to when you push off a rock under water). With Earth, I want the motion to be sudden and strong. I want the Air to be summoned with much more graceful and elegance. I feel these motions will reflect the consistency of the elements.
