You definitely delivered!
As someone who prefers more moderately-sized MOCs to huge, complex builds, I quite like how clean and sophisticated your interpretation looks, even despite the lessened scale compared to most Makutas. The color scheme is smartly limited, and the Onua Master torso is used to great effect. I like the subtle Vorox armor on the lower legs, and the Protector feet as hands are nice. The spiky armor on the chest feels a little weird, but that’s the only thing about this that I at all dislike. Amazing job!
