not bad man, i don't really have anything constructive to say about anything you should change or do but this sounds good
i'm currently posting my progress on making the full song over on soundcloud, soundcloud.com/sareed
more stuff over there.
speed up the drums a bit and get rid of the repetition in the main synth
when i first tried to make DnB i downloaded a bunch of drum loops and i would just look at the layout for them and see what its supposed to look like, then i tried matching it in FL's sequencer
its actually pretty damn simple, just kick snare kick snare and some high hats or other drums n shit
this isnt that bad to be honest its just that synth on a constant loop, try changing the chords around every 4-8 bars, drums don't usually change except in the intro and if you're doing a transition with a drum fill and outro, dnb is usually reese's, not synths like the one looping
also for the bassline, try not to loop it unless you're modulating it in some way, a reese usually has a notch filter on it and you move that band around with an automation clip
that bass actually would work better with a drum fill
currently using ignite, not FL.
FL has gotten super iffy for me
