This is a lovely song with a touching message. The piano is good and you are a very talented vocalist. I would say that you need to make the song develop further to keep people interested. Sometimes raising the key of the song up a few semitones will add a bit more epic to the song. failing that, it needs more vocals in the mix - they are too quiet and flat against the keyboard at the moment. I hesitate to say you need more instruments as I like the simple feel but go with what suits you best. Good idea for a track :)
I've heard a lot of very good songs on this site and this is also a great song. Love how you portray an intimate and tender relationship with God. Some of the treble kind of hurt my ears though, that seemed harsher in the very beginning. This is a beautiful song though, and you have a great voice!
Love the piano intro, beutiful voice, maybe a tiny bit down on the music allow you voice to shine more though I know you have skills, And would love to here a lil more expression I think you kick but, dont hold back.
