I really enjoyed listening to the album. It's a while since I listened to such good metal. However, I didn't expect the sudden shift in the first peace, maybe introducing the guitar in the background earlier could smooth the transition. The second track is cool, but maybe you could consider to integrate it in the third piece and shorten it. Leading right into the action of the third piece would make the silence at the end of two even more impactful. It does probably not fit your story as well, but switching the first to be the last would resolve the introduction point mentioned before and could lead to an even better flow. Regardless of the suggestions, your album is on my favorite list.
