Inner Dive is a strong opener, matches perfectly with the vibe you're trying to set.
Clouds of Doubt has an underwater feel to it, as if trying to pull down the bright air of the track. Really cool.
Forest of Loneliness turns a bit more mysterious, I like where this track is going.
Ocean of Fear, I like the bursts in the first half, made things quite interesting.
My Greatest Fear sounds like a nice track for conflict, definitely boss worthy, although perhaps not as a battle theme but more as an introduction to the boss theme.
I liked it overall! Inner Dive is my favourite, but Clouds of Doubt was also quite nice in how it combined things. Good job!
