This is a very atmospheric piece, definitely fitting the mood it was suppose too.
--------------------
I liked
The quality of sound. Even with the echo effect and massive gain in this song, it fits well.
The vocals, (DUH, kinda your signature :P)
The ability to make me think of the moments in the game the original song played in.
The chillness level of this song. Very soothing and calming.
-----------------------------
Dislike
Nothing really. it's a great song :D
------------------------------
Nitpick
Honestly though, I feel you established yourself as a strong enough of a musician. Personally, I'd like to see some of your own works in future time. I mean, I love video game songs (Especially those with the strong central beat) as much as the next person, but I bet with time and a couple of your own tracks, (Which you may have already made your own tracks and I just need to check :P) I bet you could create some interesting pieces.

Overall
Great job and keep up the fantastic job on your pieces.
