very clean and minimalistic design. The semiotics are working for me. You did the research and found all these languages to have in your poster. The half world analogy also can mean destruction since it looks like the death star from star wars. I wuld love to see other ideas applying this same concept of words and black background, maybe the words can form other types of shapes and make this poster a series. Although I have to say that this style of design I try not to practice, because I like more graphic dominant designs that can convey many messages at once.
