This is a hight quality rendering of a birch tree, it is very useful for your compositing work, as you can see on the video above, there is meny ways to use it, you can use a 3d camera track in AE or some 2d planar tracker or some particular generator such as Trapcode Form or Particular. The choice is yours 
I also upload a 3d model in 3d ocean soon the model is ready for render, so you can render with different light position if you need.
