Really liked Thanatos and Zagreus tracks, felt like they were the most interesting.
I did not care for Persephone even for an ambient track it was dull but that’s probably just personal opinion.
The only thing I really did not like at all was the break in Tartarus around the 2:17 mark, lost all momentum for me.
If you are still open to inspiration you might consider checking the Persona 4 Arena OST out, specifically The Junes Hero, A Pure-Hearted Beast, Seeker of Truth, The Wandering Wolf and Shadows of the Labyrinth.
Anyway good work mate, keep it going and I hope at least one thing I said was useful to you.
