Definitely agree about the bass overpowering everything else. Having a thick bass is great and all, but the other elements shouldn't be fighting a losing battle for presence over it. Particularly the kick drum, basically only hints at its existence in the upper end of its frequency range and is definitely fighting with the bass more than it should. Sidechain compressing it with the bass might help, as well as slotting the bass into the mix a little better, which I think is the major culprit here. As for the chop, i like the dissonant horror vibe it has, but in all reality its more of an ambience than a melody. I could see it being difficult to work with being that usually horror movies use dissonance to create tension.
Overall I don't dislike it. Creative use of drums to fit the vibe, but it needs some polish, and some more variation to it.
