A good read. Had never heard about the Saruv before, that sounds like it would have been good fun. Overall, I'd say you did the darn best you could have, considering you took over when the project already had some momentum or at least fan anticipation behind it. It's hard to modify core concepts once you've taken even the most basic first steps in the process.
In a little personal retrospective of my own, I definitely could have made Kaah less whiny, as some have suggested. However, that's how he came off to me when I first read his character and I maintain that it was the most natural way to voice him. Sounds like I would have had a whole other set of very different lines to do had things gone differently, but "what-ifs" are no good to anybody.
