Sounds exactly like something a lonely, non-mute Chell might sing to herself in the years after escape. :)
I liked the resonance added to your voice - helped it not sound 'thin'. I thought your singing was spot on for this song although I am grateful for the lyrics because sometimes I couldn't quite understand a word or three. :)
this definitely will be regarded as useless but...
I know a lot of this is borrowed from other sources, but this is really well-done. I love it. :)
Please contact me if you would like to use this in a project. We can discuss the details.
