Re: Evolution?! lol
Taking something I created and presenting it, unaltered, as your own, is plagarism. But I'd have no problem with you reading a comic I've drawn that someone's given you for free or creating fan fiction using some of my characters. Or if you wanted to do something of your own using a style or technique I came up with, it would be fine by me.
I'm of the opinion that no one can ever really bite your style, not if you're truly original. Jack Kerouac said, "Ideas come a dime a dozen, it's the approach that's important."
