I really like the mix of the styles. I haven't heard something like that before I think but it fits quite well toghether, or at least you manage to combine it very nicely. You use the leitmotiv between the first 2 songs combined with nice arrpegios and change it up in the 3rd song to sound more hopeful.
My favourite track would probably be "Battle Against the heart of the cave" just because the harpsichord and the e guitar combine very well + a good bass line and the second drop just tops it of very nicely.
Definetly a very cool and unique submission, keep it up! :D
