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.
