Piano Music
The piano part sounded very well done - not sure if you've played or sequenced this, but it sounds pretty natural in terms of expression. It took a while for me to get into it, but there are some really nice parts, my favorite being the segment from about 2:00 to 2:42. I liked how you did the variations around the melody, but at the same time I felt maybe a more contrasting part would be much welcomed.
Oh, as for having to cut stuff out, you can probably get away with a lower bit-rate for something like this, or better yet, use VBR encoding at quality 10 or 9.
