There is something pretty spooky about this last one. It's obviously like an old wall, but the shapes on it suggest that something was hidden behind it. It hasn't always looked that way. Carefully looking into its cracks makes one feel less and less easy. The sort of thing that scares one, but curiosity makes one really see what's inside.
If one were to turn this one 90 degrees counterclockwise, the "crack" would have a slightly naughty double-meaning...
As always, you manage to draw one into your creation. One cannot just glance at it and move on. At least I cannot. I must linger and study it, look for all the many things that are teasing curiosity, like a riddle, but also just because it's somehow inspiring dormant senses behind the eyes. Again... as always! I just love what you do.
