From around 0:17 it gets interesting.

I like the instrument selection and how they work in combination with each other and the song structure in general, however I don't think that this would strictly fall into the genre of Drum and Bass and would fit more as an experimental piece. It sounds more like something which would fit as game music.

I really like the dissonant parts around 1:08 and from there, it almost makes one think of some kind of mysterious place.

One thing to work on is building in more dynamic range and playing with silence as opposed to full sound and also the addition of sound effects and allude to new sections in certain ways, for example by risers. I also think the percussion currently is a bit dry, so maybe add some reverb to it like the reverb on the synth to make it sound more like it's part of a whole.

Good work!
