Moses continues to work through his ideas about trees and emotions.

Here is the pen drawing,

 A Friendly Tree.

The tree's expression is unmistakably friendly, branch arms outstretched and ready to hug.  Moses uses a new trunk-body figure, clearly rectangular and mobilized by the two feet.  A puffy cloud of leaves crowns this engaging arboreal representation.  The three-fingered hand that Moses favors works quite well in this context.  The circular track in the middle of the trunk may be small creatures or may be holes in the trunk.

Another ink and college rule paper:

Tree Struck by Lightning and Saying, "Ouch!"

Several aspects of this drawing grab my attention.  The tree wears an expression of intense pain.  The multiple lightning strikes hurled at the poor tree seem to have lifted the tree's crown completely off its trunk.  But, what is most interesting to me is the way that Moses has made it seem that the tree has been knocked back on its feet.  He is attempting to add dimension, I think, by creating a circle at the bottom of the trunk.  We can see the bottom of the trunk as the tree falls back and to the side.

Ghost Eye Tree with Bone Spider and Owl

Note the heavily darkened eyes and O-shaped mouth which is clearly emitting spooky sounds.  The arms on the Ghost Eye Tree differ from the regular trees depicted above.  The are wavy, wriggling as they reach for us.  The bone spider has spinnerets and a line of silk coming out of the lower part, seven legs, and a clear pair of fangs.  His eyes are overlapping circles.  The intense figure at the top of the picture is an owl, his head, body, and wings identifiable.  The creature at the Ghost Eye Tree's feet was not mentioned by the artist.
