I love the edges of the branches to face down a bit when there is faux snow on them. In Nova Scotia the snow falls in large clumps and weighs down the tips of the branches, this reminds me of childhood visions I saw.

But, if you put some of the 'tendrils' that come on an artificial tree upwards a bit, then it reflects how the tree grows. I find this makes an 'upbeat' tree. Straight out makes the tree more 'mechanical' looking, and great for serious collectors who want to showcase their prized decorations.

I don't think you can go wrong, if it feels good to you, then go for it. Hard to tell with an artificial tree, its construction is not known (no photo) then one can only guess.

I would get something to fill in the interior of the tree to hid the very visable trunk part. Inexpensive silk flowers and greenery can do this too. A friend suggested a white feather boa for me to try in my new white tree.

If you could post a photo of what you have so far, and what you plan to hang on it, that might help others to give more advice and help you further.
Good luck with your decorating and can't wait to see how it comes out!
