Almost finished...My thoughts are to put a path just off the left side and a fence. And a couple other tweaks here and there. 

UPDATE: I have added the path and the fence. (See picture, below.)

The fence did more than I expected. It added more depth and perched the tree on the left, up onto a little hill instead of on a slight slope. Still need to add a little snow or bushes around the tree on the right and see if I can, '3-D' the rock I added, on the left. Final picture coming soon!
