My favorite expressions are the one on the full-body pic of him, and the first one on the top row. I love the wide, crazy-eyed look he has on that first headshot, and the big, eerie smirk on his face, too. They work together to give him this look of crazed, gleeful delight. I like the one of him on the full-body shot because it shows focus as he's hard at work carving the stick into a spear. And I like how it's not just a bland, emotionless focus -- there's that kinda frustrated, grumpy feel mixed in, too. I mean, work is work, and how many of us do real work with a genuine smile on our face? I like how adding that bit of personality to the expression makes the action come alive even more.
