Baggronor:
I’m an illustrator and I can assure you, the copyright on anything you create is automatically yours unless you sign it away (copyright and patents act 1988 I believe.) I also get the impression copyright is a bit shakier in the US than in the UK where I am.
To be honest copyright disputes rarely seem to be hard fought, (at least in the industries where I work). The company I work for make a killing out of tracking down people who have used their images without permission and suing them. You can apply for proof of copyright, buts thats mainly to establish a record of the date. Owning the original is enough unless there is some kind of other contracts involved (this is why Illustrators should never hand over originals).
www.calibancomics.com is my website, but its all illustration for the moment. I’m working on a range of miniatures with the intent of setting up a small company but this won’t be for a while.
