The only thing I can truly nitpick at is to keep the piano lead consistent with the fade-outs, to go with the original. Maybe a little more focus on dynamics, since those are pretty apparent in the original, as well.
Other than that, nicely done. I suppose you weren't going for a completely faithful cover, since the percussion was a bit different than the original piece, not necessarily a bad thing. I hadn't realized how much was actually going on in the song 'till I had seen this cover.
