holy composition i enjoyed this. really cool.
feedback: i know you dont work in a daw but a little bit of mixing could really help your stuff. just a compressor and a limiter can really pack the sound together so the quiet and loud parts dont jump around.
i really like the whole journey and all the places the piece takes the listener. but as the track goes on i dont feel like this could belong to an end credit scene of a game. listening to it makes me feel like it’s made for a certain scene of a movie. idk maybe it’s because it’s classical.
idk how Sibelius works but controlling dynamics of each instruments is essential, when some of the notes are being played and they hold and they dont change expression/velocity much, it feels a little unnatural. with a daw its pretty easy.
basically im saying with the type of skils you have, get in a damn daw.
anyway hope that helps. wish u the best.
