Looks awesome! My only criticism is you should have a manger scene somewhere.
I've thought about it, as well as a star, and a cross. I'm torn because I'd like to get the focus on Jesus, but I also don't use statues and stuff. And I was worried that it would look like an afterthought, and the colored lights would detract from the manger.
I've seen some really nice mangers though, and if I could do it tastefully (meaning not those plastic lighted figurines) I would like to try.
I even know where it would go, not directly in my yard (where it would look like it was competing with the garish light display) but rather over with the clear-light holly tree where those 4 deer are standing. A much more "solemn" setting. Maybe next year -- I'm running out of room for new lights anyway....
