Overall, is was a really solid track; nice groove, good sound design. The one and only complaint I have is that it kind of lacked a melody.
I understand that DnB isn't about lush chord progressions and a musical mosaic of notes, however, it needs something to get the blood pumping before the drop. Those four chords you used were really good in the beginning, but it needs to grow from there before the drop comes in. 1:46 is a pretty good example, however it lacked variation in my opinion.
Aside from that, very good. I am especially impressed that this is your first DnB track, and out of the gates it was so solid. These are just my opinions, and good luck for the future. c:
Right now I'm kicking myself, because for some reason I never even thought of adding a melody. XD
I totally agree I should have added one, and thank you for the great review!
