Good Start

This track seems like it's a good starting point. What I mean when I say that is it feels like it should vary a little more. Like this track is the basic for more stuff to be added later. I like the DIRTY ASS BASS LINE, but I (personally) wanted some moar whomp whomp in there. But that is just me. Also, to me the kick is completely being swallowed by the bass line. Maybe adding a duck/gate to the bass so it ducks every time the kick hits to give it more clarity and punch. Also add more reverb to the snare. For dub-step (especially) you want to drown the snare in reverb. It's almost demanded in that genre. Hope this helps.

zero bombers are a-holes

this def needs some more work tho. vary the bass melody, the bell sounds nice. I dont care for the growling synth tho. I would also change the melody up a bit
