Worth pursuing, but needs some work
I'd suggest, for your own peace of mind, avoiding the sequence on that Toxic Biohazard sound, simply because it's from the base presets. I'd recommend changing up the waveforms and the sequencer steps here to produce your OWN sound.
The bass works, but isn't dynamic nor dirty enough in my opinion. You'll want to find a way to work with the frequency cutoff, perhaps add a little "room reverb" (just a little bit to give that bass some edge), and maybe add some distortion and drive (you can check out some of my dubstep songs to see what I mean...while I'm by no means "perfect," I've been able to get some pretty edgy sounds outta the bass through experimentation).
The drums seriously need some work. In fact, this is probably the biggest area that needs some work. There isn't enough going on here. The kick doesn't stand out enough, and the snare is too "acoustic." To fix this, try layering the bass drum with a sine wave, and layering the snare with a tuned-down clap and a quieter electronica snare sample, to give your drums that extra punch, so to speak. You also need some more hats; I would recommend experimenting with getting those hats on 16th-note intervals, giving your drums a little more character; of course, don't just put the hats on EVERY 16th note, but vary it up in interesting ways. You also need to add some fills and varying drum parts, because although you've got the dubstep beat right, this is just the BASE. I'd also recommend increasing the tempo slightly, as it feels like the slowness drags the song behind in energy a little bit.
The basic melody is very cool, but could use some expansion. And I like that swooshing sound you use to transition the movement, but the song needs some work in areas. The first place you should start is with the bass, followed by the drums. If you've got any further questions, feel free to PM me. You've got a great idea here, you just gotta finish it!
