For this set of MADZ avatars, the theme is Halloween.
Trivia: I sometimes do characters based on my friends just for kicks(and it also saves me time thinking about extra characters). A good example of this is the Bakeneko, the cat girl which I based from Neko, one of my org-mates. If I know you, then there’s a good chance that I have included/will include you somewhere in my works somehow. LOL
