Its a Avatar wanna-be!
Actually this is pretty cool. I love that lightning part and the blurring at the bottom of the image, kind of blending things together. Its pretty cool.

Edit: Don't regret it. This is a wonderful piece and obviously has nothing do to with Avatar. For one, he never did anything with lightning, at least to my knowledge. And two, you can tell its a original piece. I love it. Those people who complained just don't understand that you can not copyright monks or Elemental powers and if they end out in the same masterpiece, like yours, it doesn't mean its Avatar. Just because it made a big hit with some people.

P.S. I was joking when I said Avatar wanna-be, by the way. and I added this to me favorites;)
