Nice opening. It works quite well for what you want to convey I think.
Arcane Green is quite relaxing. I like the tonal shifts. Keeps it interesting. I think this is my favourite. Also really like the solo string near the end.
I also thought "A path back in" was quite interesting. At first, it seems like such a gentle happy sound, but then the heavy use of vibrato becomes very dark and foreboding. It contrasts so starkly that it works very effectively.
Good job!
