Certainly :)
From what I took from your interpretation, the last song would be a grand finale boss which you overcome, and I never felt that.
The final harmony is of accomplishment, all good, but I never got that feeling of "grandeur" / victory, it was more like a level mid way, which could be what you were going for just fine, but the piece before is so tense and "heavy" I felt the last song would be asking for something else, something "more", more threat maybe, felt a bit underwhelming.
As I said it probably is my favorite, honestly I think it would stand out more as a standalone it has a lot to offer already in itself, with the other tracks there I'm expecting some continuity, even if different styles, the narrative should be present and I feel it was not quite there.
Hope this feedback is helpful, take care :3
