Very nice totem.

Ideas:

1- You could try creating a bigger tiki using that one as a pattern.
2- Invent a small ambient with people worshipping it.
3- Hue the white with any smooth color and play around with bushes and a nice sun (all of these with the same kind of colour :D)
4- Make a large image using small pieces like that tiki.
5- You can turn that into isometric and do that kind of stuff.

Im out of ideas :/
