Well done.
The muffled "sound" is probably because the quality of the song had to be reduced. It's 5:30, 128 bitrate that would be around 5.5-6 mb's.
It is an exceptional story however, I enjoyed listening to it greatly.
It seems a tad cliche however, the overall type of vibe from this song has been a tad overdone, however that means nothing in the quality of the work.
I really liked your choirs. I would be careful with that volume control, I know the effect you were going for, like the washing of vocals, but the degree you did this at was too severe, it cut back and forth far too much, it would have been better if you just kept it a stable note.
Loved the strings, i'm all about the strings!
It has a very defiant feel to it for sure, I love it.
You must tell me where you got your choirs ;).
5/5 from me madboss, keep them coming, great work here.
