In the first painting it looks like the trees have abstract faces on them.
BINGO! As I looked at that first painting with this in mind, I found faces and abstract figures all over it, not just on the trees. Unless you look with that in mind, it is hard to see, but the subconscious notices and kicks us saying, “something funny is going on here...” Now that I see it, I can’t unsee it, and I can sit here for a long time finding lots of thing in the picture.
