OK, good attempt at an abstract, but I think I want to see a little more focus in this before I'm willing to accept it. As mean as it may sound, this almsot looks like an accidental shot that you just decided to enter. The only thing that makes me thing otherwise is the way the color shift is pretty evenly horizontal.
I found this a very beautiful picture, but it also seemed to lack some kind of... oompf for me. I ended up giving you a 5 because, while it was technically beautifully done, I really don't get any emotional response looking at it.
the color here is nice but the contrast is a little weak...shots of the sky are tough if there is no distinct subject other than the color gradients. = 5 - jmsetzler
