Your music is really awesome!
You've got so many different moods and themes that fit perfectly with the areas and situations they're written in. The instrumentation is quite beautiful in all of them, I would say to expand upon this. Play around with some really slow and really fast tempos, different scales and modes (if you know music theory), and just have fun!
I would like some feedback on my music as well: https://grasselementalost.bandcamp.com/album/grass-elemental-demo-demo-ost

I would use this pack, but I make my own music. I do really hope someone will find it useful, I'd recommend 100% :)
