Hey..
Just heard this song.. I think it's still ambient-ish genre, maybe that's what genre you're destined to make =P. (Joking)
To be honest, I'm not a fan of dissonance in music, it makes sound awkward. I think using more harmony is better, to my taste.
This song's a bit repetitive, but you've done a really good job building up tension in this song. Just that the ending was a bit sudden, the song didn't have time to break down. The weird noise that pops up didn't really did much.
I think this has some potential, if you add more melodies and such. Great job on this. =D
