That's pretty Oots style. Its not maybe exactly what the giant would have created, but it fits the aesthetic. The flail, maybe, isn't clunky enough, and the skull-mask could look more like an oots smiley face. But I don't remember how oots handles flails, and there aren't a lot of masks around, so its not like its violating some precedent.

Just my two bits. I like it ;P
