I hesitated a long time before I replied on this.
I want to make one thing clear : thank you for freebie and wanting us to share it.
Because I don't want you to discourage you to post new items in the future.
But I have some remarks on your tree: It hasn't  enough branches and needles, I don't know which modeller you used to make this tree, and I think it will be a hell of a lot work to make it by hand, but please be more critical to your own work: take a picture of your own or someone else tree, and compare it with your model.
I hope I wasn't too rude.
