An interesting contribution. I think I get what the other commenters are saying about the third track, a minimalistic battle piece could still work but might need more tonal variety or maybe some different layers of instrumentation to really come through. I can hear your battle theme working well with an Anna Meredith-styled minimalistic orchestration, in the style of maybe something like "Nautilus". I was getting those kinds of vibes, so I could hear something like that working here.
