Woah, neat! Excellent references. This may sit in my computer's saved files for a while before I do something with it, but 8D I will link back when I do.
These are definently useful, or then I'm the small exception here. It's hard to find good references for special emotions and expressions. Making collections with a lot of them makes the finding job way more easy, at least for me
I'll save it for when I need good references!
I wasn't sure if anyone would actually use these... But if so, I've got a bunch of people who are interested in sitting for similar sessions...
