To help promote Operation Moonfall, deviantART group MajorasMask3D organized a character collaboration project that began in February of this year. As you can see, we have a wonderful mix of styles, coloration, and media covering many of the characters featured in Majora’s Mask.
However, there are a few characters missing! If you would like to help contribute, feel free to contact the group admin for more information. Let us make this bigger than what it has already become!
