I like that the pointy bits of Orde’s mace are a combination of modelled spikes and actual Lego pieces. Too often a custom weapon will just be a purely-custom model without much use beyond the figure it was made for, but this one has some customizability to it.
Overall, though, all three of these models look pretty close to how I’d expect these Toa to look.
It is the mask of adaptation made by Rothanak. I put the link to the thingiverse page in the topic.
Galva’s and KhingK version of the mask are very good, but I prefered to use this one. In my opinion, this design is the most accurate recreation of the mask seen in the ignition comics, and it gives me the feeling it could have been designed by lego.
