Almost there!
The following image shows work on the horizon line:

The next image shows work on the tree. More and more leaves, except I removed the spruce branches that were playing peek-a-boo on the lower trunk.

When I painted over the spruce branches, it left some texture, so I decided to change up the horizon line a bit.

Next week is my final week of work on the painting.
Time to zhoosh up the forty elements! 🙂
