I like it. I like how you went with a 90ish% black instead of rich black. I like the mechanical looking paths this has. It's clean looking and I like the splash of color but it could just as easily function as a one color. The circle in the center reminds me of registration marks, even without the crosshairs. Check the kerning a little bit and make sure all your gaps with the symbol match. Some of them look larger than others and your subtext looks like it needs to nudge down a couple of pixels.

yea i really like this too! i think you should take into account what Jon has said above. I feel everything is to tight together at the moment and things need some room to breathe, so i would loosen it up a little by moving things apart from each other a little bit. You need to re think the subtext because if you get this produced on a business card for example you wont be able to read it.
