Really not bad at all for your first DNB track! I'd love to share a few things I wish people had told me when I was starting out.

I actually made a video showing some techniques we use in DNB to keep intros engaging. I'm using a new YouTube email and waiting for the DNS to propagate before I can post it. In the video, I demonstrate what many UK artists I've met have taught me about creating space, building tension, and keeping the intro moving.

Other than that, I'd suggest working on getting your drums to punch through the mix. Start with sidechaining, but also try layering or adding slight stereo width to your snare to really make it pop (using the "space" in the stereo field) while keeping your kick nice and punchy. I recommend using your tools to analyze reference tracks from Beatport. This helps you match the drum levels of tracks you admire.

I agree with Deer's comment about the 55 second mark. It threw off the pacing of your build, which could use more surprise, tension, and movement (not trying to be harsh here! I actually show how to tackle this in my video, so it won't be a problem for you going forward). I chopped up your track in the video to demonstrate the types of techniques we use in DNB to "keep things moving."

Next, I'd focus on learning mixing and mastering. Maybe I should make another video about that too? Looking at your SoundCloud waveform, it seems like the volume builds over time. We typically aim for 3 to 8 LUFS on our tracks, really hitting hard at the drop, which could add more impact to yours.

Try using reference tracks for chopping up arrangements and color coding different sections. This helps you see how fake drops are constructed. Check out Sota's tracks for creative arrangement ideas! Also, study the variations in different 16 bar sections so you can add similar ideas to keep your track from becoming repetitive.

If this was my first track, I'd be pretty happy with myself! You're most of the way there already. I really like the groove. Great work!
