Ok, I gave it a listen. Not bad, really. The sound could use some work, but nobody can expect you to have highest quality studio sound, of course.
I don't dig the black-metal-ish vocals too much, though. I like growling and shouting and Converge-style-incomprehensible barking and everything, but not black metal vocals ;D.
The video could be a LOT worse than that. Pretty good job there. Still looks quite amateurish, but whatever. I've seen much worse videos than that. But the Golf 5 and all those other new cars in the beginning kinda spoil the atmosphere ...
