This remind a lot of the theories of a multiverse, and the other universe like bubbles with different realities inside. My bet about the guy in the triangles is on the time stages: Present, Past and Future, in that order, but I could be wrong. Probably I said this before, but I love the golden and silver combination. The silver is for me a symbol, a gateway to other worlds. And the gold here is like an Alchemist with the philosophical stone, the very essence of life.
Great work as always, my friend, fun to interpret as usual .
Just a little thing: I feel the skull in the last triangle is in a angle maybe too different from the other two, I feel it odd. Maybe is the one in the middle that need a more demarqued angle, I don't know... maybe I'm just overthinking this too much. XD
