I checked like 20 random pictures and it's safe to assume that *b.* is a person with eyes half-closed and *c.* is same with eyes closed. Now check this out:
Update 20: 908 blinking pics out of total 1532 (thus leaving only 624) could be easily removed with absolutely no impact on the story/content.

Don't get me wrong, I'm not saying that you're a liar or that you're needlessly exaggerating the number of the renders. You could have just added a blinking face next to the text the person says and it would have freed up a lot of time.
Man, I really love your girls, they are pretty, but I feel really sorry that so much time and resources are wasted on rendering blinking characters instead of actual content that we could have seen.
