Keep the space between forest and empty ground in good contrast. There should be more foreground with the trees more to the back. Keep an uneven space on both sides.
	The side with the smaller trees should have more space, and gradually taper away. The taller side should be closely spaced and show a sharper grade.
	One unit of forest planted radically to the back corner.
	Two units of forest planted so that the trees on both ends will keep circling back into the forest, creating a movement.
	Three units of forest planted with the same movement in mind.
	Taller trees in front, medium size in the middle and smallest toward the back will create better perspective.
