Alright, I'm going to be brutally honest with you here: I found it quite hard to actually listen through this piece. Although combining orchestral music with EDM is an interesting combination, it is a very delicate one that must be approached with extreme care, and unfortunately I found the quality of both elements to be quite lacking in this piece. I'll break it down into two sections.
Composition:
- When using classical instruments (including choirs), try to consider the position of the players themselves. Right now it all sounds very robotic, and lacks any form of human emotion that is so important for orchestral music.
- You used the same melody over and over again. Don't do that.
- You used the same harmony (chords) over and over again. Don't do that.
- There was quite a lot of dissonance, which made it sound "unpleasant".
- There isn't really a common thread to follow: the sections all sound very arbitrary and random.
- Be careful with the amount of layers you use: too many of them and your mix will sound cluttered.
- Voice clips can sound gimmicky really quickly. Use them only if it adds value.
Mixing / Mastering / Other technicalities:
- Clipping (sound levels too high; lower the output volume next time or use a limiter).
- Compression levels are too high (when side-chaining is active?).
- You should give the EQ another look: not enough spacing between the instruments, and the highs are too... high.
Pardon the wall of text, but I hope it'll help you improve for future works. If I were to give one final piece of advice, it would be to study some more music theory: that can really up your level and understanding of music quite a bit. That said, all in all, a 2/5 for the effort.
