Thanks for all the feedback. I'm probably going to end up doing a live recording, as I have a pretty low-end music composer. That will take care of the "humanizing" and the accents to keep with the waltz style, also helping with the dynamic variation. I'll also add some more original material/new harmonies. I'll try to get the "updated" version by next Sunday-ish minus the humanizing part (as I'll need to find a place to record) but I'll try to add in some original bits. Again, thanks for all the feedback. More would be appreciated, especially if it hasn't been said here yet, but not necessary.
