See - it didn't take many trees at all to fill the space. After finishing the mockup, I spray-painted all the objects to mark their location. I'll then be scaling the resulting 'drawing' down to about 14x11, which will be the final set design that i'll take to the shop. One catch with this whole process is that my mockup camera has a narrower field of view than Dave's camera, which is 64 degrees. However, I have taken this into account, because I am so goddamn smart.
