This is a spin-off from my other series, Sound Doctrine. For more information on these characters, check out http://www.webcomicsnation.com/ramblingfriar/doctrine/series.php?view=single&ID=169941 .

Not only are the backgrounds different colors, they are different gradient patterns. There are other subtle differences, mostly accidental, and if you want to keep yourself amused for longer you can try to find them. Don't bother telling me what you found, though.
