I like it. Good work. The organ really put this song up on a higher level than others. One thing though, be careful of those really low tunings. Sometimes they can kill a song just because it'll make it sound like any other death metal song (this song is death metal btw, melodic death).
Very good. Nice and groovy. Great work with the organs too. Overall good songwriting skills. Your riffs are a bit simple though. You should maybe try a bit of variation.
