Pretty good
Pretty good, nice and atmospheric.
My only complaint would be that the drums stand out a bit too much, I don't know what it is but they don't seem to fit too well with the rest of the song. It would have been cool to see something else keep the beat rather than you're typical bass and snare, like mechanical sounds or the sound of something striking medal (Something that would sound more like background noises).
Anyhow, great job.
