ok that is true with that though. I like my first though. I think these fall under the title of fan art. And with fan art the ideas of the original are protected, but the use of them on a free fanart idea they are allowed to.
I think what I am really trying to point out is that fan art is not infringing on copyrights of the original. If it was you could never draw a picture of lets say Goku from Dragon Ball series with out paying money to the people who own him (dont remember the spelling of the guy's name and not even going to try
)
