When I first conjured up this cover art, I had a single song in mind that struck me in particular -- "Courage," by Christopher Tin. In general, when I wasn't drawing from Osamu Tezuka's influences, I was getting inspiration from Christopher Tin's discography. Given I created this cover are a good while before I started work on the webcomic proper, you may notice minor discrepancies in the character's designs here and in the comic.

By the way, I guess I'm going to sprinkle these descriptions with trivia from now on.
