Compression is your friend. There is a lot of really intense peaking in some segments which I don't feel like was your intention

The melody at 1:20 is seemingly just random notes that just really mud up the mix by adding a pretty high Frequency in without any consideration for the low end, which is already very saturated at this point.

Would be interesting to see the workflow for this track, it's not bad but it feels really far from finished.

The drums aren't too bad, I do actually really like them! Tho, to be honest, I feel like the kick and snare should be more punchier, and I don't really feel like the percussion you used in this song fit that much the DnB style.

The bass notes you used definitely need some compression, they sound too loud to the point they sound distorted.
The melody that starts at 1:21 is also too loud, and it's pretty much just random notes that don't really let you get catched to the song.
The sound at 2:34 feels really out of place and it's also pretty loud, tho I kind of like the really reverbered and delayed percussion you used after that.

I don't really like how after ending at 3:00 the song abruptly starts again at 3:04 out of nowhere. This time ends up a little better, though.

I think you wanted to go more like a liquid DnB style, tho I'm not too sure since I don't really know that well the DnB subgenres, but if you wanted to go for that, I would recommend you try to use punchier kick and drums and a reverbered piano alongside a synth bass.
