I know you were going for a slow and ominous start and all, but I think the instruments at the beginning needed some more reverb for the full effect. Still, I like the sense of climax throughout this piece, even though it is really short, and the instruments complimented each other really well IMO. Especially around :35, there was a clashing chord or two, but I think that only aids the mood you were going for. Very interesting work! Keep it up, man. ;)
