I had a tough time with this guy. One step forward, two steps back. The uv unwrapping was quite easy to do, but during modeling the morph maps I didn't recognize I messed the uv layout up. The mesh flow around the mouth is not the best for modeling facial expressions. It took me a long time to close his big smiley mouth and it still has surface issues (not in this picture). I changed the texture and the size of the iris today, much better.
