EDIT after got your response: (and all of this becomes completely useless if this post was just a meme)
Okay here you go:
1) Let's talk about arrangement: just boring halfbar change in 1 bass without any bg stuff except sub is too simple, it doesn't sound interesting or heavy or headbangy, try to add more shit in general here including other basses, bg synths, cymbals, hats etc. Without them it'll suck
2) Mix and sub: try to transpose the whole thing to E-F# (if it's already in 1 of these 3 keys, just move the sub octave down) because that's where sub sounds the best (and how sub sounds is extremely important in dubstep, whatever dubstep even this one). Currently it's too high pitched so it makes the whole thing sounds weaker than it really could be. Kick and snare sound fine except samples themselves are quite chessy (not really a problem, just my opinion on them). Also the sub should be quiter because currently it takes up quite some attention from the main bass synth
3)Sound design: Uhhh, 1st of all I want to point out AGAIN that having just 1 bass without anything else is not good. It sounds extremely boring and weak. Add some more stuff and try to go more aggressive than this one because for this kind of repetitive vibe it'd work the best. Get some growls here, get some rough neuroish basses, don't stick to this thing from early 2000s, it just doesn't work in this context. Learn sound design and go deeper into bass design.
