This's pretty jammin', dude. I like your basic riff, and the leads are pretty sweet as well. The bridge-type section that comes in at about 2:52 is killer, and same with the one at 3:40-ish. It's laid back and energetic at the same time, which seems like a contradiction, but makes for a good mix. The dirty bass is definitely a plus. Lovin' it.
One of the things that I didn't like was that a few times, the song feels like it's coming to a head, like at the end of a build-up, but then results in something a bit anticlimactic. I dunno if that was a way to keep the energy of the song going, but it's a little off-putting. Also, sometimes it almost seems not energetic enough to match the dirty, in-your-face tone of the bass. Maybe if the drums picked up the slack during some parts.
Either way, now that I've talked your ear off, damn good song, keep it up. (:
