One of the things I always like in a series is its gradual change. I hate it when they just stick with one design for characters, keeping them wearing the same thing and having the same kind of hair and whatnot. It makes for unbelievable characters. Plus, if fans get too used to one look, they tend to dislike future changes the author might want to eventually make.
This is why I like to gradually change things in each episode. For one, the clothes are always different in each episode. I plan to eventually just cycle through the same couple of outfits per episode, but even that helps breaks up the monotony.
This section will document changes in characters over time and subtle things you may or may not have noticed in the character design.
