It could make PRO.
Amazing... absolutely amzing... a great feeling of depth and desolation. This song is one of my favourites but it has a few flaws which can be straightened out, first the vocals unless im incorrect are too vague and unclear, they're mushy if you know what I mean, if you can't simulate the choir then get some people to sing for you females are the best and have single vocals instead of choir. ALso a bit more orchestrals, more string backing to come in at certain intervals and blend in and out; sort of like weaving... you make things come in and go out with an absolutely stunning effect believe me. If you do this you can make this song fit for a film or professional class music track.=)
