I thought I would work on this one which I can stop at any time with no clean up required (see post on 12 September 2018).
I started at the top and put in all the pine tree tops that appeared above the treeline.

From there, I put in the tops of the trees at various levels near the top of the hill.
Next, I indicated the base of the hill and the path the road followed.
The last drawing, I was able to do was put in the grasses and growies along the roadway.
I will post this at a later time once it has been completed.
Thank you for coming to look at my artwork.
