WOW, that's a lot of lights! This appeals to me largely because of the composition. The lighted trees lead the eye right into the photo, and oddly enough, it looks almost like they lead to a TV (that tiny blue rectangle). One of my favorites in the challenge.
I moved this one around a bit before settling on 8. The trees and silhouettes are very interesting, but I think it would have been better to get a lower angle to include less ground and set the forms of the people more in the lit tree background. I also find the small bits of color visible in the trees and directly down the path a bit distracting. Still very nice and one of the better shots in the challenge.
