I liked the intro , preety dark sounding , wow nice riffage there mate..
The tone is too fuzzy though , not a big problem though .
sounds good . great riffage , nice harmonics here and there , nice drumming beat .

My only advice would be to fix your tone , and add vocals..

LOL : the ending is cool man , i liked it..keep it up mate.
