I was going with this set for a tribal polinesian look, because OM reminded me of a fat maori firedancer. I actually did no reference sketches for this one, i mostly googled some images, and used those as references. Kind of lazy, but I didnt have time at that point. Anyway, here are some pics that I used
The weapon, a maori Waihaka.

The hairstyles
And the tiki ofc.
Highpoly sculpt in Zbrush, I dindt really care about the feathers, since I didnt need a custom normal map for those.
I made the hair texture darker than the original hair color, and the feathers got a red tint, to match the heroes original color theme.
And finally an ingame test with all the masks. I only used the specularity and rimlight channels for this object.
I take it you're from newzealand?
You should give them full facial maori tattoos
