In response to a question on Tumblr, I am very happy for people to create fan art of my monster characters in the Real Monsters series. As long as credit is given and you show me the outcome then that's all I ask. Id really love to see how other people may interpret my designs or even the disorder. You could draw your own versions of the mental illnesses I have designed for and I would love to see them!
Boring but important bit:
The designs are copyrighted to me, so please do make sure you give credit to my original designs if you reference them in the work. If you decide to create your own versions of the mental illnesses, then I would love for you to reference the real monsters project in the comments etc so other people can join in if they wish.
If fanart of the designs is not credited, I will hassle you.
(and of course you cant make profit from them)
