Great song!
For an ambient piece, this is very well written indeed. :D
It does get a little bit repetitive at times indeed. But I really don't think that it's a problem at all. It works well for this song. I can certainly see this song being used in an animation. Probably being used in a movie in which a protagonist explores underwater ruins. Your title certainly suggests that.
Great song! And great to know you're not dead. :P
