Hey man, the song is...interesting, the beginning reminds me of Opeth's "In my Time of Need" (and Damnation in general) but with more wackiness a la Mars Volta, and then gets, well, a little screamo sounding (though I guess that's mostly the singer). As for the mix I really like the kick, and the ethereal lead guitar is cool too. I guess the only things I'd change are the snare volume; it seems like it needs more compression (and make-up gain), cuz sometimes it's a nice volume, but other times it's too soft; and the strummed/arpeggiated clean guitar that comes in at the end of the ethereal-lead part (before the screamo part) seems really dry, like it could use some verb/delay. And I actually really like the thunder sound effects.
Oh, and is the amp you used for the distorted parts a Rectifier? Cuz in the end, when things really start crankin' up, it sure sounds like one.
