The elaborate patterns make me initially think of a sea shell
I think it could be - a lot of natural structures have this pattern.
However, I can clearly see the abyss. All light, hope and prosperity getting dragged and consumed by this plume of darkness. Everything with motion gravitating towards that singularity to experience nothingness and gloom. It also looks like a hollow tube leading to somewhere. Despite how ominous darkness may be, it is also an exciting mystery.
Yes and it could also represent an internal void. Thanks for your kind words.
