Diggin' it.
I like this, you've definitely got skill and you know your way around whatever program you're using. ;D I wish I had that knack for blending instruments so they complement each other: yours do very well. (:
I really dig when the whole thing starts going at about 2:33, it's got a pretty sweet vibe to it. However, what I didn't like was that huge, tension-filled, frenetic build up - that took half the song, and then left me hanging after only a minute of rockin' the beat. I think what I didn't like about this song was that its proportions were off; INSANE build, and then a relatively tame, short section of real stuff.
You might also give it a little more atmosphere after the build, maybe another instrument or two to flesh it out a little. Just a suggestion to maybe play around with! Nice work on the whole. (:
