Kagunk, Ogre Chieftan

This Kagunk, Ogre Chieftan (3164) from Reaper Miniatures. I've had it sitting on my desk for a while and finally finished him up. I've pretty happy with the miniature. He's mounted on a 50mm base. Why a round base? I'm looking at more skirmish rules for my fantasy gaming and I'm a fan of LotR rules to start with and I hear A Song of Blade and Heroes in another good system.
