One thing I thought of is an icon or symbol for the site so people can recognize us easily! I noticed some Anime sites use an custom anime character.
-In order to show energy green/red hair in a crazy style can symbolize this. The character looks full of energy. :
-Or the relaxed mood with long straight hair that is blue/purple to bring calm feeling. With a mono-expression face. :
Of course there are many possibilities with this. I just thought it would be good to make a "commonplace" for people to respond to.
