He's got a very serious face. No happy-go-lucky Treebeard type guy, this one.
I like the details Otherworld included, such as the mushrooms growing on him and what not. They give him a lot of character.
He does seem a bit grabby.
Up next, a pair of pack horses from Reaper Bones (I think). Nothing special, but they will get use as part of a pack train in a game of Chainmail.
