I'm sure this is an age-old argument, but I'd like to bring it up again because I always appreciate advice and information on what I do.
The topic being Selling Fanart.
People do it all the time, at conventions, online - they draw characters from computer games and shows, often in their own style, and sell them on for money.
Now, my question is, is this practise legal?
In my own set of commission rules, I say that I cannot draw copyrighted characters (though, that should probably be "trademarked characters"), but truth be told I would actually love to sometimes.
Is it a question of legality, or is it one of ethics?
