My Christmas Tree Photo

I had the idea of creating a christmas card using my camera and a sparkler. I have recently been taking alot of night shots with long exposure and thought that I could create a christmas tree.
This photo was my second attempt.

I have entered this picture into a number of photo contest and have received positive feedback so far. The picture has also appeared on the Reuters website in the photos of the week slideshow as the #1 picture.

Now what do I do to top this next year?
