Hi Jen,
Very beautiful beam formation, reminds me of Star Trek..:) btw I had time to look your other works and pictures, an amazing gallery you have, especially tornado and the kiss..:)
This is a little too simplistic for me personally. I do think you used a nice gradient. It's a good idea though. I would suggest playing with the initial design more to bring out more detail.
I adore the colors in this! It makes a nice, simple background, too. Sometimes you just need something basic to balance the rest of your life out, right? lol.
Nice one.
