Love the piano arrangements you did for the tracks, really stood at to be expressive and complex. Think the piano you choose suits the idea at hand, has the felt-texture and a lot of organic noise to fill the space in.
The dubstep was definitely suprising, but I like how you fleshed out the main melody within it. Only nitpick would be the cheering part, I understand the narrative, just needed some side signal from reverb to make it flow a bit better into the mix.
Overall very nice experience!
