This is soooo good! The ideas here are awesome! I really believe every track here at least has the potential to be great, if it's not already.
It's easy to hear you have a solid grasp on composition and music theory. I love your use of time signatures (I'm a sucker for 5/4) and interesting harmony.
Also, a special shoutout to the battle theme for being so groovy it hurts!
I'm really glad you were able to be submit this ost, and I reaaally hope you decide to finish and polish it, 'cause it's genuinely fantastic!
