Snow Fall and Christmas Tree - My Second Moving Graphic in Photoshop

Here's my second moving graphic experiment. This one is snow falling on a Christmas tree that I Photoshopped last year. Looks okay, but the snow is too one-dimensional. I'd like to see another layer of falling snow behind this one, to give the graphic a better sense of depth.  Feel free to use this graphic anyway you like.  Update:  I fixed a hiccup in the snow so it falls more smoothly and realistically.
