Here comes my version of a Wookiee Chieftain. I converted him heavily to stand out from the rest of my Wookiees.
I used mainly parts from the new Wookiee Warriors expansion, combined with a spare arm from the Fluttercraft Bombardier. The Vibro Axe on the back was build from scratch, using different 40k and Legion bits. I also gave him a Wookiee style helmet.
