Thanks everyone for your comments, I will post an updated pic of where I'm going with it sometime later today. It's taking a long time to render now.

Catlin: I did a tutorial on the tree's, and right now I'm having a problem adjusting the moss on the trees so I might be stuck with them like that (the moss going all the way up the tree).

You can do the tutorial here.
