The bell pad is very nice and the whole intro sounds very good.
The beat is original and surprising, which is cool. I find the last part less successful. More dissonant and messy.
If I may give some advice:
On close chords, it's harder to make them sound low. It's better to make open chords or to place them at the higher octave. Otherwise the sound gets muddy quickly.
For the tonality, when I read that you had started the locrian, I was very curious. It is clearly the most complicated mode! It's very hard to stay in this mode without being drawn to Ionian or Aeolian.
Well, I can tell you that you have been sucked into the Ionian mode. You are not in locrian D but in ionian Eb. You can hear it at 25" where your music becomes conclusive and you stay on the Eb chord.
All in all, congratulations, because it is bold to try this mode and your music sounds good despite my criticisms :)
