Overall, the song had an excellent sound which clearly had a lot of effort put into it. Well done!
As for feedback, I loved the strings, but I think the percussion could've been better. Roughly 2 mins into the song, the drum cuts out and it returns to the strings. For a better build-up, they should have stayed in for the rest of the song. At the end (3 mins 40 secs?), the cymbals come crashing through and the general mood is lost. Without the gradual increase, they sound painfully artificial and immersion is lost. :(
As usual, any improvements are up to the artist. I hope my input helps in some way. I'll be sure to take a look at your other stuff! :)
