I'm with 1031fan -- he looks cool, now he needs some of the uniformity broken up. Also stain him to make him look weathered and messed up -- coffee and tea are good for that; mist (don't blast) here & there with black spraypaint to look mildewed. And dont forget to stain the twine/rope that's tying him; a lot of people forget that part. And something dangly from the hands... vines, ratty rags, torn-up stained cheesecloth, whatever -- something to hang and sway in the breeze.
That's a groovy mask... where'd ya find it?
