aight: the sweep sound is pretty anoying, I noticed you panned it which proves eye for detail (so thats positive). how about making the sweep longer slower, and less static (more evolving and more background than so upfront) basswork is nice the drop (klimax after the intro) is kind of weird, it doesn't fall right in the structure (it should be moved half a bar or something I think)... dnb is pretty predictable in that view: the drop falls where people expect it which leads to crowdrespons (I know this tune isn't meant to be played, but its more a tip in case you want to make more dnb tunes in the future) try rolling the breaks a bit more, instead of 2 times 2 HH's & a kick between two snares try two times a HH and a (volumed shorter) snare and a kick (so 1 hh & 1 ghostsnare which together take as long as the main snare)... maybe scratch the HH's during the snare as well it kind of gets you out of the flow some nice experimenting overall keep up! ps: for that roling sound it always helps to "layer" an existing break (f.e. an amen) on top of you own break...
