Very Intriguing...
This really has an amazing quality to it from the very beginning. I do think the intro went a little long though. Maybe tighten that section up a bit.
I'm not crazy about the guitar part, but it is the feeling and mood you are going for. So I won't hold it against you. You did well to create an ambient metal piece. Although I'm not completely convinced I would say it is ambient. But that is just me.
The melodies are awesome man! Really, you have written some great melody lines. And how you've almost hidden them in the tune is a very cool feel.
The drums really fit the style you were going for as well. Nothing too complicated, but they changed enough to keep from getting stale. Nice job on the drums.
I love the section around the 3:40 mark where the guitars fall out. Very classy touch there man. Very classy indeed.
The mix you created is nearly perfect. I really love where everything stands in the mix. Everything is clear, yet leans on the rest of the ensemble to really fit their purpose. Very nicely done on the mixing for sure.
Now, my only real beef is the quality of the guitars. It sounds like they are FL Slayer guitars. I don't want to hold that against you, because I am forced to use them from time to time. But still, the guitar parts are pretty simple and laid back. I'm sure you could find someone to record the part for you if you can't do it yourself.
But as it stands, this is a very nice and fulfilling song. Great work!
4/5 and 8/10 overall. I really like the atmosphere you created.
Best of luck on future projects man!
