I can suggest you to listen to artists like Goreshit, he´s an artist that makes REAL Breakcore.
Being honest, This ISNT breakcore, just atmospheric Drum and Bass, that is because Breakcore is way more chaotic and more BPM, artists like Sewerslvt, Tokyopill, etc make this type of songs, but, this is a great attempt to make breakcore.
---------REVIEW---------
The amen break is very well mixed, the atmosphere is very good, the synth gives the song an unique Feeling, and the effects are very good too.
But in my opinion in your next you can give the song a little bit of Piano and some bass but is Good.
Final Result:
Mixing: 10/10
Effects: 9.5/10
Instruments: 8/10
Final Score: 9.8/10
Great Song!
