Update: Postergirl bonuses:
If you can make her have different expressions (minor face variations kinda like this:

I still don't have postergirl pics! And even when I go get a candidate, I'll announce a margin of time for those who might come in late before making a final choice.
I also got hold of a dude who can make a gameplay video for you guys. It will be a little briefing of the game. Awesome.
