Hey there! Nice tribute to the game :D

Just a few things which maybe can be criticised:
- I Think it would optimize the piece to bring some Cembalo in - that would increase the ancient feeling.

- It would be a good thing to integrate some deep drums / percussions to make the mood more evil and to support the brass section (i think i can hear some timpani, but they are to week because the brass and string-section - which is good - is to loud and suppresses them). Try out some deep synth-bass-variations - maybe its useful!

- Bells would give a mystical touch

Anyway i really like this homage to castlevenia. Good work!
