I really like the sort of drone-like and pensive quality the first minute or so of this one had. It also was pretty climactic and all with the harmonies that started coming in around 1:43. Your pieces don't really have a lot of dynamic contrast in them, but that might be easier to fix once you start incorporating more instruments into your tracks. I really like the whole "countdown" idea, though...I thought that was pretty creative. May I ask what program you use to make/record these tracks? ;)
