What an intro!
I love the vocal pad with its slightly varying pitch. It creates an instability counterbalanced by the solidity of the rhythm and the D that doesn't move. You've added lots of little sounds to enrich it, it's a real work of sound design and it's magnificently well executed.
This whole first part is clearly a boss of a souls-like.
The second part, on the other hand, may have a well-written melody, but it breaks up the boss-fighting aspect.
Nevertheless, it's an excellent composition that I'm going to study carefully to understand how you made your great intro/1st part.
