This is the canon wiki. And there are about 30+ skin ideas on this wiki in the mainspace. There is a wiki about ideas of this game (which was founded by me), and if it still works as it did last year, then you make the skins and post it somewhere, from where it is taken into consideration (not sure about this last point though, if I am wrong, someone correct me).

This will be open till 10 October.

Also, write your opinions too.
