I love the thought you put into the purpose and narrative of your songs. It's always a good feeling to feel like you're composing with a purpose. You do a great job at it. I could definitely see your story in my mind while I listened.
Your orchestral VST is a little on the weaker side, but that's totally fine. My main criticism of your EP is in the mix, theres too much low-mid (80-200Hz). And your music loses a subtle clarity due to the mud. Just managing your EQ a bit better would improve this. Chapter 5 has a lot of mixing issues, the sounds are just not coming together nicely. It sounds like you may be just turning up your drums instead of side chaining them as well.
Keep working at it and you'll go places. Good luck in your studies!
