Praise to you, sir!
This is very good stuff. Actually i have nothing to comment about, it's brilliant. The only negative would be that the only thing that makes this a non-opeth song is the clean vocals. But you do this really well so it's all ok

You'll develop more of your own style with time, and for the moment you've got obvious composition talent and playing talent.
The clean vocals at 18:00 were a little offputting, but the rest were good. You guys can get really far if you stick with it and get a full album's worth of really good songs, especially once you start getting a bit more of your own style.
Almost all of the song is as good as anything Opeth does, but my only comment would be that your song didnt peak my emotions as much as Opeth do.
Also, for a 20 minute song, that flew by and never got tiring.
GREAT work! You are going in my sig
9/10
