Hey, this is really neat. I can definitely sense the personality in this one haha. I really like how you handled this, it's not too often I hear people using movements in their Newgrounds submissions.
If I had to change something, I would say maybe recheck the clarinet in 01:02. I feel like the second note in that may sound better if it were raised up a note or a semitone. It would make it sounds more appealing to the listener while still having its menacing effect and giving the feeling of war and pain. Although I don't exactly know what it will end up sounding like since I haven't tried it, I do recommend playing around with it to see what works best with the rest of the harmony you've composed.
Overall, I like it a lot! I hope you keep composing music because I do think you have a good ear for it :)
