Well, it's certainly... interesting.
I have a couple comments and overall impressions:
1) When you write music, you should really try to make a complete framework of the song, and then fill it in. Otherwise, you're going to have the problem of "Here's A, Here's B, Here's C, etc, etc". Good songs with inner cohesion are not done without extensive planning. This also applies to classical music. Therefore, what you should be working from is an overall sketch of the entire piece, not just the "here are the first 40 seconds as I want them to hear". Get your planning done, lay out your framework, and then fill it in.
2) Why is there no transition between the drums and little siren thing and the bassline? If you're trying to go for the "abrupt" effect, I'd still have something on the downbeat (that's the first beat) of the measure the drums cut out. This would also be a good place for a filter effect.
3) That mini snare-roll you're using in the back beat is pretty obnoxious. If you're going to keep using it, try playing with the panning, so it's not always hitting the center speakers only, every time. The alternate speaker approach can really make a piece come alive.
4) I know this is only a demo, but take a look at your levels. If you're going for the grungy, shitty speakers, I'll destroy your bowels approach, then it's working. Otherwise, you may need to back down a bit on the lows, push the high, and move elements off of center pan.
I'm not a big techno fan. The lack of actual melodic material tends to annoy me more than it does excite me. The "minimalist" concept of most electronic music is lost on me, since I prefer minimalist "classical" music. I'd consider listening to some Phillip Glass and Evan Breyers.
