A very dark orchestration with some interesting twists and unexpected turns. The main thing that bothered me was the off tune notes. After the pause, nothing really seems to go well together. I see you were trying to create an interesting song with an off key theme, which works sometimes, but in this case I don't think it turned out so well. instead, sadly, the melodies seemed to blend in in a chaotic, mish mashed sort of way. Your timing was great and things were brought in just when they should have been, but the actual composition wasn't very enjoyable.

My advice is to focus more on what strange chords go well together. Dont change pace so quickly. Progress slowly, slowly building up with strange, unexpected sounds that go well together. Then, climax to the speed increase instead of slamming it down. Go about things slower and the off tune idea will work well in my opinion. Your mixing is well done and you mastered everything as well, so props for that. Just work on your melodies.
