I'm gonna say I'm satisfied with at least 3 of them(Kongu's, Jaller's and Hahli's mask).
I didn't like the fact that 2006 included some sorts of plain boring "mask holders" instead of a new real head. I know that in the story, it has to do with the special power of the mask of life or so, but for now I'll keep that away from my artwork. So here are my representations of my masks, hope you like them. PS: They are not 100% accurate representations of the 2006 masks, but the global concept is still included.
I won't make the bodies, too much time demanding, and I think that they are the most boring part of the minifigs. Let's hope that it reaches Trending, or whatever it is called.
