D'kota Hill Tribe Barbarian

Took a break from my OD&D scribbles to try one for myself. I am working on a setting using the Outdoor Survival map and my house ruled OD&D set for an upcoming Flailsnails game I may run on google+. This drawing is of a D'kota Hill Tribes barbarian. My setting will not use much in the way of humanoid monster types, humans will fill that role - but the dungeons will be full of odd and creepy monster types I am sure.
