Some pretty great tracks that capture the feeling and themes that each track attempts to convey really well! I don't really want to repeat what others have already stated, but I can definitely see some possible improvements in the mixing (although I completely understand because mixing is also my weakness lol). Aside from that minor critique tho, I really like the composition and choice of instruments. You did a great job all around!
Overall just some amazing work in general! You did a great job capturing the different emotions and themes you wanted to go for and I applaud you for that! If I had to choose a favorite track, it'd probably be "Last Stand In A Hopeless Battle," but that's really just because of my love for boss battle themes and orchestral music in general lol.
That's all I have to say really, have a great day!
