Somewhere I stumbled on an image of a printed page of character designs for Yuri Petrov, Origa, Lunatic, and Legend. Linked here:

I don't know where I found this image, but I like this better than any other set of character designs I've seen for these characters. I'd be most grateful for information on where this page originally appeared.
