He looks pretty good so far. I look forward to seeing the completed moc!
As for the eye color, pretty much any color would work, in my opinion. I suggest making them green or blue, just so there’s a little more contrast between the mask and the eyes.
Yes, he canonically wielded a scythe. He also wore a volitak, and didn’t have silver armor, so perhaps this would work better as a Toa Defilak moc.
Regardless of it’s accuracy to canon, the moc looks quite nice
I like the asymmetry, and how the shoulder armor’s design mirrors that of the pakari. I do, however, think that the ccbs shell on the torso sticks out a bit since they aren’t that many other trans-orange pieces on the moc.
