About the original COS,

Since the definition of cos is still being discussed in the circle, the following is just my opinion.

I think a more formal original cos refers to, for example, a cartoon or novel created by oneself, and then this cartoon or novel has a certain popularity, and then the author carries out cos according to his own design.

But now it seems more open.

If it is anthropomorphic, it seems that it is necessary to give a human figure, and this human figure must have the characteristics of the real thing, and then it must be accompanied by a cos diagram when it is released.

If you read a novel and then want the characters in the cos novel, I think, first of all, you must know whether there are any official characters in the novel, or whether you have made TV dramas or played games abroad. If not, you can set your figure according to the characters in it, but when you publish it, you should still give the name of the novel, the name of the author, the figure of the characters, and mark the originality. If there is an official who designs TV plays or games, he really doesn't like those settings. He can be set according to the characteristics of the role, but he still has to do the above when he is released.

This is my understanding. . . I don't know if you will accept it. . .
