With the excpetion of the rage class feature, this seems more like a native-american or jungle dwelling aborigine rather than the classic nordic fighter that most people think of when they hear "barbarian". It's not necessarily a bad thing, just a comment on how you seem to be mixing flavor from 2 different classic stereotypes.
P.S. I like the animal totems, any chance you would consider adding a few magical-beast totems? Maybe as LA+ versions, like a dragon-totem barbarian, or perhaps just upgraded alternate versions of other totems; the horse becomes a unicorn, the lion becomes a displacer beast, etc.
