You have composed many music for this game but there are a very few of them which give me the old RPG vibe as Azys La, Zurvan theme or some music from PotD (imported from 1.0, so composed by Nobuo Uematsu + T9 1st part).
What I feel by listening to them is the sensation of "mystery", "strange" and his derivatives.
I like very much this kind of music because of the use of a synthesizer, I guess.
So, would it be possible for you to create more music like that in the future for area, dungeon, boss and more ?
