This is really, really well made considering the time constraints and how long you've been doing this! You genuinelymight have some hidden musical talent that was uncovered thanks to these jams, I'm kinda jealous lol. You must've practiced a lot for this to come to fruition. When I was 1 year into making music I was still figuring out how to add reverbe to multiple instruments in my song without crashing Cubase lmao.
The main theme works really well, it may not be the most groundbreaking thing ever, but it sets up the mood perfectly
I've already commented on your battle track in the server, but I noticed you've added a lot of embelishments to it that really make it pop. I especially liked the whimsy touches near the middle
Eryndor's Madness was really something, it felt really cinematic. The violas representing the hero was a really nice touch, and the build up was amazing. I'm not sure how I feel about the battle theme coming back, at first it felt a little abrupt, but hearing it evolve into a completely different song sold it for me.
I hope you come back to this project and add a few other songs to finish your vision, cause the stuff that's there is really something.
