Very interesting!
Your use of vocals reminds me of a lot of other techno-ish music with vocals, especially the pitch and intonation of them. It seems that a lot of male vocals for techno songs have that strange pitch modulation, audible at around 0:24, 0:25-ish. I never quite understood what was up with that, but it sounds good anyway, so I don't mind much ^^
Anyway, time for the review.
Intro - Well, it introduces the song nicely, but it isn't very long and cuts right to the point (and the lyrics!), so I think its job is accomplished well enough. It certainly wasn't absent, it just could have been a bit longer, maybe. Not too much, your length worked. (2/2)
Body 1 (:45ish until 1:30) - This part is kind of generic, could use some spicing up. I'm no musical expert, I won't pretend to know what to add to it, but it needs a bit of something. (2.5/3)
Body 2 (1:31 until 2:15) - This had a nice beat, good rhythm, rockin' melody, but it was perhaps, once again, a tad too short! Maybe lengthen it out another 15 seconds, give the people what they want :p (2.5/3)
Falling Body (2:15-2:25) - Just a bit of a winding down, but adds a new instrument nonetheless. (1/1)
Outro (2:25 to end) - Well, it ends the song, and roughly as it began. Gives a nice feeling of coming back to the start of things. (1/1)
Total Score: 9/10. Needs a bit of improvement, but a great song overall. Voted 4 and downloaded.
