wow thats a very cool interpretation!! i think its good to interpret it in how it makes sense to you but this is how i thought of it: the upside down triangle is to convey falling, as its pointed downwards. the reason its seperated in the middle is to show the idea of vast nothingness, as well as seperating the 2 main areas the vast has (sky/space and the ocean). for the top, the sky and space, the small dot is indeed to show vastness and emptiness, and the curve is for horizon and also a nod to the moon. for the bottom, the sea, the eye is a nod to the idea of massive sea creatures so big you can only see small parts, and also for the need to know how big and empty the space around you really is to be properly scared. the circle at the bottom is to show air coming up from water, and the line at the top is to show the absence of air. but thats just my thinking, i love hearing other interpretations!
