Lacks colors. Lacks variety. The very end of the song is where something is really happening, but then again, I can sense some kind of fear of experimentation. Don't be afraid to take risks.
Edit 01: Before the in-depth stuff, I have to make you notice you also use samples.
Now. to help myself (and you too) going deeper in your soundtrack, I decided to decorticate it:
I- Intro (00:00:00 to 00:02:30) A perfect intro.
II- Verse A) 1 (00:32:30 to 00:56:30) You made a musical segment and duplicated it so it can last enough for a verse. The only variation is at the last 4 notes of both segments, so there's something that can be improved (you could take risks). Except that, it works fine.
III- Chorus 1 (00:56:30 to 01:08:30) The most awful, yet most important part of the song. It is less "lively" than the verse, so you should invert the "life" you put into chorus and verse to never loose the "breath" of the song. Just imagine that the song breath must blow calmly yet not too much for the verses, intensely at the chorus, calmly at the bridges and badass at the solos.
IV- Verse A) 2 I (01:08:30 to 01:20:30) It's the exact first half of Chorus 1.
V- Verse A) 2 II (01:20:30 to 01:32:30) It's the exact second half of Chorus 1, but you added some synth pad melody (it's called a melody filler) to make the repetition less boring. Even though, you still didn't save it from the monotony of the repetition (you could take risks).
VI- Bridge (01:32:30 to 01:56:30) A perfect Bridge to create a variation in the song.
V!!- Solo 1 (01:56:30 to 02:29:30) I give a 9/10 for this section. You truly show your tremolo, bending and dropping skills. The only thing I found less interesting was the long notes without effect that were put to fill the lack of creativity between your awesome parts. It's really a tiny default that you can legitimately underlook and keep going.
VIII- Solo 2 (02:29:30 to 02:41:30) That's a solo filler you should be worried about. Arpeggios-like solos can be really effective if you take more risks and keep it less repetitive, so I'm sure it could be so much worth improving. The whole solo part would gain a lot of power (you could take risks). I do create some of my arpeggios note-to-note to be sure I make its dynanism going crazier. Of course, it's not every composer that can seize it and I'm modest enough to admit I can get issues about it.
IX- Solo 3 (02:41:30 to 02:47:30) Your talent is back at this section! :) I smiled to it. You even composed something more intense for the other samples, so you blew it.
X- Chorus 2 A) (02:47:30 to 02:59:30) The counter-time rythm of the battery composition is great, but could be even more chaotic to really throw the song end in a powerful blast (you could take risks). The chorus main melody needs more legato in it's downs, so you could make it more intense, yet not too sostiphicated.
X!- Chorus 2 B) (02:59:30 to 03:10) The solo filler is too weak for that moment of the song. It must to blow everybody away (you could take risks).
XII- Conclusion 1 (03:10:30 to 03:16:30) The second best part. It's the necesary conclusion that concludes perfectly the song.
XIII- Conlusion 2 (03:16:30 to 03:17:00) You tried to make it a conclusion, like many American composers of the 20th Century. You could just remove it, since it's a short repetition of the same note for each used sample. It's exactly where you could make it a 4-notes crescendo.
CONCLUSION: You perfectly mastered the introduction, the bridge and Conclusion 1 and you almost perfectly mastered the solo. But... You messed up more or less all the other parts (the necessary ones, such as the verses and the chorus). I'm looking forward in your next creations / remakes and wish you to take me seriously (by the way, thanks for your critic on my submission for the competition).
