Ok well yeah this looks more realistic as far as I can tell. Still looks like it added the kind of variety I suggested (e.g. "zib zib doo" -> "zib doo zib doo") whereas an actual artist would come up with other kinds of variety (e.g. Glass uses other kinds of "additive" techniques like "sul na, sul na doo, sul na doo re, na doo re, doo re, doo re..." etc). But that's probably nitpicking since you're free to do whatever.

EDIT: "doo doo la" -> "la la doo" looks a bit more "creative" since I don't think this is a suggestion I made (unless you added more examples to your response). So, yeah not bad.

EDIT2: Nevermind, I did use that kind of transformation in my example (1) above: "doo zib zib" -> "doo doo zib". In short, it seems to have vaguely understood that the point of repetition here is to emphasize transformations. But it should be able to come up with novel transformations like Glass does.
