Track 1: Cool opening track, for some reason I feel like I'm about to play a round of Call of Duty Zombies... very intense, with some lovely crunchy harmonies!
Track 2: I love how one track tapers into the next! Another very interesting-sounding track, which I believe is in 7/8-- love a nice mixed meter!
Track 3: good stuff! it's very similar to the first few tracks, so I'm hoping there will be some more variety in the coming tracks.
Track 4: this track felt slightly repetitive to me-- don't stress about making tracks really long. As long as you say what you want with the music, it need not be repeated too much. You have a great voice as a composer-- trust yourself that you don't need to repeat things too much, okay?
Track 5: ah, this is an awesome one-- it's not very long, but it's full of energy, cool synths, interesting material, and a great sound. I loved it!
Track 6: another really cool track with that epic Stranger Things sound. All the wind and noise really gives it an eerie feel, as though evil creatures are approaching.
Track 7: I loved when this track ramped up! It somehow sounded like flamethrowing a sea of corrupt humanoid monsters... which I imagine is just what you were going for... it's modal, in an interesting mixed meter, and just a downright banger. Love it!
Track 8: This track feels like it belongs at the end of an Episode of Stranger things, for sure.
Track 9: Awesome final battle music!
Track 10: a great conclusion to a dreamy synth-filled soundtrack, and I enjoy how closely each track is linked to the story.
I appreciated your use of mixed meter and crunchy harmonies throughout! Every track sounded great. Keep writing!
