This was one of my first projects. I made it last December in 2.49 just never posted it. I used it to learn the particle system. The only things modeled are one light two ornaments and the trunk and branches.
I like it, are you participating in Andrew’s challenge? If you are, good luck!
What challenge?
why the Christmas competition of course 
which explains why you have probably seen quite a few Christmas themed posts lately. First prize is a kindle fire
