@Leath: Drastically altering facegraphic poses for different expressions is an idea most definitely in the pipeline, you can be sure they'll be posted here (possibly merged into this image) as soon as they're produced! Another thing we hope to do with the face graphics is have them represent any situation forced upon the character's sprite ingame. For example, should a character be struck in the flank by a speeding arrow or stuffing their face with fine beef casserole; we intend to represent this in the face graphic as well as the ingame sprites.
This does all take a great deal of time however, and currently our focus is on other things, such as neat'o battle sequences.
