That MoC is very cool, but alas, we’re still gonna opt to not allow for the Vahki piece. When you bend those restrictions, it’s too easy for people to sneak all sorts of designs through that could bend things way too far. Ultimately, we do have the power to veto stuff, but we like to restrict that to absolutely necessary cases. Keeping things in parity with existing Metru sets allows for a more streamlined process overall.
If a winning MoC/artwork uses an existing BIONICLE mask, our idea is to mandate that being kept in the final group shot illustration. If a custom 3D printed mask wins, the artist will be given the OPTION to either redraw it as a custom one or keep it in the final group shot (as the prior contests have done).
Yeah, that should be totally fine! Good question!
