I'm finding myself really impressed with this one, I love the chord progression and atmosphere in the beginning. Those pads and chord are really well done. Also, I have to compliment you on the choice of bass and percussion, they fit well with the rest of track. With this being said, it's pretty repetitive. This aspect works for it until around the 3:00 mark, where I begin to get bored of the same chord progression. The mixing is also slightly off. It's a little muddy and the sidechain time is set a little high. Overall though, this is just a simple yet interesting piece with great attention to detail.
