Returning the review...
Pretty nice stuff you have here. :P I rarely review because it's tiring to do - my reviews get really, really long every time. This is good, though, so I'll give it a shot. :P
Great start, I hardly ever hear songs started like that. :D Nice intro section, it's got a fair amount of energy, possibly a bit too much? You don't want to start with too much energy, otherwise you've got a long way down to go to your first breakdown, which can be difficult, or nowhere to go if you want to build higher while keeping a good progression.
Your bass synth is good overall. Good choice for the sake of this song, however, I think it didn't have enough going on in the bass area and too much in the low mids, which means that it didn't have as much boom, but still took up the same amount of room in the bass area as it would have otherwise, leaving little room for the kick. :\ When making basses, you should choose between a mid bass (something that plays low notes but doesn't have any bass to it, leaving the most amount of room possible for the kick, see my song Falling Farther (Trance Remix)) or a bassy bass (something that has a good amount of bass boom to it, while leaving room for the kick). Try not to go too far in between, kinda like you did here. :\ In the end, you want no distortion/clipping/crackling/etc., which is still something I have trouble with myself. :P As for your actual bassline, it's close to, but not exactly the same as, the 1-7-6-6 (going down the scale) bassline which I find good, though extremely overused, which sadly kills it. :\ It's a bit too close for comfort for me... you might want to make a more complex, melodic bassline than that. ;)
Synths and composition are all decent... one synth I especially like is that somewhat distorted synth playing in the mid ranges... a creative touch, which is nice. :D Great idea with the triplets here and there, too. It plays a bit too much, though, there should be more parts in the song without it... I get tired of it easily. :\ Maybe you should work it into your progression so the song doesn't start with it, but it shows up later on to build energy before the breakdown? Your pads are good, too - they're simple, which is good for the sake of having your own sound (see next paragraph). I THINK I recognize that lead from Nexus? The Store N' Forward expansion? I might be wrong, but I've heard it somewhere before... once again, refer to the next paragraph for why that's a bad thing, though in this case I think it fits your sound and this song.
I don't think your bass-ish synth that you introduce at 2:02 was a good choice, sadly. :\ First off, I feel I've heard it somewhere before, which is never good. It bends the sound of this song, which should be yours (your style, etc.) to the sound of that synth, which isn't. If you've got your own sound or style to your songs, that's one more thing people can like about your music. ;) Of course, don't rush yourself in trying to perfect it... I'm still trying to find mine. ;D Second, I can't say it fit that well. :\ Third, it's another synth that's somewhat, but not fully, a bass synth, which is a problem - a good rule of thumb to follow is that you should only have one synth playing in those ranges at a time, for the sake of leaving room for the kick, or just for the sake of avoiding distortion and clashing notes, which can happen in the low ranges even if normally they wouldn't clash. Otherwise, either the kick will get buried, or it'll distort the song along with everything else with bass to it.
Drums could have done with some polishing. The kick didn't distort, but ended up getting buried under your bass synth (and the other low synth in the second half of the song). The clap was overpowered by the rest of the song, and I think I recognized it from VEC. Once again, don't rush yourself in developing an original sound, but try to steer away from using raw samples to using heavily FXed and/or original samples. Hihats were good, though also quiet. No complaints on FX and crashes, great job there. :D
Out of space, continuing in a PM... XD
