As I was going through a box of partially completed drawings and decided on doing a little more work on this one (see posts on 20 December 2016 and 25 May 2017).
Using a pencil I indicated more trees into the background; and then I added more layers of bushes and growies into the foreground before moving on to the large tree's branches and leaves.

Next I started inking in the background trees and added a little more of the fence on the horizon before starting on the bushes in front of the foreground tree.
From there I worked my way up the main trunk of the tree and along the first large branch; before I proceeded to work on some of the leaves in the lower branches.
I will post this drawing at a later date once the tree has been completed.
