I think the roughest part of this arrangement is the first 50 seconds. It seems to meld together a bunch of ideas and styles that don't really mesh well together in my opinion, and the tempo being all over the place gives the impression that the ideas were executed first without really giving any thought as to whether or not they would work as one unit.
But once it hit the 1 minute mark, your trademark metal style REALLY started to shine through, and the song started to feel a lot more complete as a whole. Once the tone had been established firmly at that minute, the rest of the song became much more cohesive in terms of style. The piano finish was a nice touch, but I feel like as an intro, it doesn't really help the listener come to grips with how the rest of the song is about to present itself. Going in, I expected a softer piano take on Falling Down only to be greeted with hard hitting sounds at about 30 seconds that didn't mesh well with the wonderful piano piece that the song started off so strongly with. However, the mastering and the drums, particularly at around 2 minutes really get me jammin'. Overall, I think very highly of your take on this song despite some criticisms I've laid out. It's very clear you had something in mind, and did everything you could to bring it to life. In that respect, I believe you succeeded.
