Hey man, you don't HAVE to upload every single track you make. If a certain track is being a pain in the ass, just put it off and work on it at a later date. And when I mean a later date, I mean whenever you feel like working on it. Don't force yourself.
Anyway...
- this track is more breakbeat than DnB...but they're more or less related so ignore this asdfasdfadf
- It's really soothing. And nice melodies, too. Sounds like something from The Sims 3.
- Try glitching that beat a bit more like you did earlier in the track. Don't over do it, though. Or you could try varying the beats slightly near the end (like removing the hats or kick).
- Give a few seconds worth of silence to let that last note ring a bit.
