Model Facial Expressions

[karmagarda]

I've seen the page about model poses which is very helpful (here), but wondering is there a "facial expression" equivalent? I've done a search but can't really come up with anything very good. Something similar to this stock photo, but it's not exactly what i'm looking for. I'm looking for something more "model face poses" or something. Something a bit different to the norm... so apart from going through loads and loads of individual photos... anyone have any good links?

Thanks!
