Finally listening to it...
I'm with Mitgong--you have your own sound, in a really cool way. All the different styles sound right for the genre, but I can hear common threads.
The denser mixes hold together nicely, too, and the instruments still sound life size. I like a lot of the drum sounds, as well--big and roomy but natural.
The only criticism I can think of is a bit of digital-ish harshness in the high-mids of some of the heavier guitars. That could be from the MP3 format as much as anything, though.
Really nice job.
