Basically, what I did:
Use the "No" emote, and wait till she looks to the right with her mouth closed (it was at 541 frames for me, and don't worry about the arms, but if they do show up, they can be cleverly erased). Pause that, and then just wait for her eyes (the wierd pupil bit) to look to the right too. Then just quickly screenshot that, and the rest is Photoshop!
And here's a pic of the settings + pose (lazily cropped it in MS Paint... so tired..):
Tip with female Humans (the ingame models, damnit!): It's all about the direction of the eyes.
