Listening on cans, so I'll just ramble while I'm listening. Keep in mind, I don't play, record, or mix music of this genre, but I do listen to it a bit.
Listening to Dark Side - very cool stuff. The effect samples you have goin' on there are cool as hell. I'd like to hear the vox a little more - they sound good, but they're too low. The hook could be a little fatter sounding - I like what you have, but it could use something more IMO.
Listening to Rage & Aggression - that guitar work is crazy cool - almost retro 80's, but not in a stupid way - it's cool. I can hear the vox better this time. I like the panning you're doing with the vox as an effect in certain spots - helps bring it up & in your face a bit.
Listening to Losing My Mind ...love the Matrix clip - be careful though - you can run into legal problems is you don't have permission. Don't like the bridge? on this one - too stacatto - leaves me hangin' too much - needs something else to fill it in (IMO).
Listening to Kick It - wow - very different sound altogether - a bit thinner - I'm sure you were using different equipment on this one. The groove is decent. The retro dog-bark thing at 2:30 is cool. Sound quality lacks a bit on this one.
Overall: Very cool stuff. Mostly, the guitars could be a bit "bigger" - if you have tracks to spare, you could try doubling them and panning. Listen to how much bigger Dark Side sounds at 1:11 (if my mp3 clock is right) - you're playing similar tracks on both sides and it fills out nicely. You've got thick effects on most of the vocals, which is cool the way you've done it, but I think you've got a few frequencies stepping on each other. You might want to analyze the frequency space the vocals are taking up and carve out those frequencies from some of the other tracks - probably both guitar and bass.
...just some ideas - great stuff.
I really dont have very much equipment at all.
