I keep seeing your work just for the last couple of days so it looks like you were gone for quite a long time as I've been following the art tag for a few weeks already. Anyway, it's so good that you're back as I love to see your paintings. You are master of layering and creating dark atmosphere. You say that you wanted the viewer question where the illusion begins and where it ends. And this is what you achieved. It's difficult to see and it makes it interesting. I also like that you included the bull (?) in the center. It looks like it is at the end of the tunnel, thinking if it should stay inside or if it is safe outside.

Great painting! Congratulations on your curie vote!
