Hooray to more Drum and Bass! Not too shabby of a first attempt! I've definitely heard worse. I think you've had the right intuition when it comes to bringing the melodic ear candy forward compared to other DnB styles, and you've also contextualized the vocal samples, which weren't made for this track specifically, fairly decently.
I would have perhaps liked to hear a bit more sauce to it, like perhaps synth lines and pads that open up as the track progresses, giving you a sense of emotional intensity and resolution. As it currently stands, it sounds a bit incomplete. The drum break is there, the bassline is there, you clearly have a structureโyou just need to add more to it.
Again, as a first attempt, I still found this enjoyable and there are plenty of elements (mastering / production / sample work) that suggests you're moving in the right direction, should you continue to pursue this line of work. ๐
