So sometimes I make non-regular show related artwork. For example I made this mask! I made it for this onimask project by Camille Young. They’ll soon use these masks made by different artists to help fund the creation of more blank templates: http://onimasks.tumblr.com/ They also have a twitter with updates: https://twitter.com/onimasks
You should see some of the others on there. They’re awesome. Hilary Florido (from Regular Show and Steven Universe fame) also made one.
You can scroll through the pictures and read the captions to see what’s going on.
Also I just bought Zelda: A Link Between Worlds for the DS and noticed there was a Majora’s Mask on his bedroom wall. Awesome.
