I'm getting a very old-style feel, like stuff I hear in tokusatsu series and films e.g. Ultraman, Kamen Rider... you have good melodies, and good chords, but there is no change in loudness that it sounds like an 80s MIDI. I don't know if that's a good thing or a bad thing. Perhaps it is bad, in the way that there's no climactic finish -- every section has the same amount of tension. It sounds almost stereotypical for a piece of this genre, too -- oppression can take many forms, but this song gives me an idea of a fight, or danger, or some sort of emergency, withoutmit necessarily reflecting oppresion.
You build up and resolve quite well, coming back to the theme you introduced this piece with. I can sing it in my head and remember it. Props to you for this.
I'd have appreciated a bit more volume control for each individual instrument -- it all sounds like it's blaring through the headphones throughout... it otherwise sounds bland.
5/10.
