I really like it, and serendipity, but I was just looking at a comment you posted on one of my pieces and then lead me here :P.
The volume seems a little.. low, it could be my end so I will not pull from the score for that.
Some of the key changes are ... harsher.. not all a bad thing, just not my cup of tea :P. I know some like more of a "sloppy" (not in an offensive way I hope) kind of delivery. But anyways, nice piece and keep up the good work.
