The voices are really nice, and the editing you have done to them creates a very relaxed ambient feel. The guitar riff is enjoyable enough to be looped as many times as you have. The songs structure is simple but that helps me feel as though i am travelling on a journey and the end of the song has a sense of arrival. I'm not sure what to critique, perhaps, i think, the guitar could do with some equalizing. It sounds a little twangy at times.
Thanks a lot!
