nice effort. I am liking the main riff,, it fits there nicely. maybe something little more could be added as opposite to this main riff.doubling, tweeking, and so on :) that Fx/noise sound which hits now and then is also nice:;
production part of thing could be better, as was mentioned above when you want to leave it this mminimal way, sounds need to shine much more.. track could be very nice after some final tweeks and sorting;;
