Dark, but also haunting. As you stated this is very simple, but it works nonetheless. You've got a knack for the spooky, that's for damn sure. The atmospherics are wonderous; Those pads near the end are like icing on the cake. I can't tell if the lower frequency noise is a part of the synth or just a standalone element, but it adds nicely to the track.
Regardless of the repetition, this is a fine piece of work Kelpie!
