i have a question, how do you get trees like the ones in your images. in particular the ones with just a black tree outline like the ones in this image you posted

is the tree background added in photoshop or are they models as well? they look gorgeous

Oh yea, it works very nice. It often makes the render pick up more details in the corners. But I'm vary of over using it.
The Dirt map is also nice.

can i ask what the Dirt Map is and how i can use it?
