I'm liking the composition and ambiance but in the drop I'm finding your kick and snare are really thin, especially your snare. When making DnB I'd suggest choosing a more impactful snare sample, and a thicker kick. I also recommend using lots of auxiliary percussion like hi hats playing a fast, syncopated rhythm to really drive across that "fast" feel. Lastly in general I feel like the track as a whole needs some more sub bass. Overall I like the feel you were going for but there's some work needed to make the drops more interesting.
