In March 2015 I held a contest for readers to design their own yokai, with two winners having their characters drawn into the image above (the drawing will be updated once the winning designs have been drawn in). There were lots of lovely entries, all of which have been posted below. It was so fun to see your designs and every one of them was wonderful. Thanks for your participation, everyone!
You can find the original post for the contest on my Tumblr.
