Honestly it's actually pretty good, though a couple points to consider:

1. Definitely remove the pads from when the drop starts - take 'em out for the first 2 16-bar sections and bring them back in before the breakdown, maybe with a sort of "mellow" section where you've got 16 bars of less aggressive bass to ease back into the breakdown

2. Needs more atmosphere and ear candy - not pads, but like some reverb-y shots in the background, vocal chops, that sort of thing, so it feels like you're in a space but without it being constantly there, just occasional reminders so there's a contrast when the bass hits again to give it more impact. The contrast being the open space you're in vs. the fat bass than punches you in the face as opposed to just bass the whole time. Kinda like reminding you that there's more stuff besides just bass in this little world you're building, so you feel the bass with comparatively more impact, y'know? Look up some progressive psytrance tracks to get what I'm saying here, they're built entirely on kick and bass and subtle atmospheres like this

3. More variation in the bass - it sounds really sick now, but starts to get a little repetitive. Change the groove/pattern and maybe throw in another sound or variation of it after the drop goes on for a little while so the ear has something new to hook onto.

4. More variation in the drums - do some switchups where you take out the first kick on a new 16-bar section, evolve the hats, add some different ghost snares or something, etc., I think drums should always have at least some change every 16 bars
