As ever, it's difficult to judge just how much someone's work has been seen. It's particularly so in this case as this image was shared on Twitter by Hope Nicholson, associate producer on the upcoming Lost Heroes documentary. It may be that very few people interested in the character have NOT seen it.
Doesn't really matter, because I'm sucker for anything Nelvana. :-) Adriana explains the inspiration for the piece on her tumblr. Give the image a click to be taken that page.
