Yeah, am looking into set driven keys at the moment to make the tongue poke out when the jaw opens, go back in when it closes etc, not too sure about rigging the eyes as they are just a solid shader and won't have pupils or anything, so may leave that for the next character.

Might look into rigging his eyebrows and mouth properly in the future too. Have only had a few days of learning rigging so am trying not to plan too much at this point.
