Interesting idea
I did kind sort of feel throughout the piece a sort of descension from heaven to purgatory, but I don't think hell was quite intense enough. It might've worked better if you made piece longer though and even more gradual, then near the hell stage your really increase the rate of change to create the sensation of literally being dragged into the depth of hell. I'm not sure what those little plucking sounds are supposed to represent, but if they are seeds of corruption, one good idea to top them off is for the hell stage, actually make the chord that you use enharmonic with them so as to symbolize their full fruition. But still, really interesting idea, and you do pull it off interestingly with only limited resources. Nice job.
