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!
Please contact me if you would like to use this in a project. We can discuss the details.
