Attached Link: A good example of what I'm trying to do

I'm trying to do an image that portrays a dense jungle canopy from above. It would have ancient temples poking out and morning mist. However, I can't seem to find the right settings for the replicator to get that impenetrable jungle canopy look with the trees. Is the replicator even the way to go with this? How should I go about this?

Thanks.
