Very nice composition! You did very well transmitting your feelings of the theme to your piece.
I was able to hear and feel almost exactly what you wrote in your fit the theme text before I even read it, so I applaud you for that!
The main advice I have is that there is some strange compression or volume changes when your voices come in to the mix. Its most noticeable to me at around 18s and 1m38s and it seems to mostly affect the lyre more than anything.
