I love a lot of the art here.
But just a pain-in-the-ass note. Some things that a poster labled as kopyleft include images that were likely made by someone else. Unless every part of your art is kopyleft, none of it is. In real life, lawsuits can verge on the insane and still win. I don't know if this has happened, but technically if you include a part of someone's ear in an image and someone identifies it as their ear and hasn't given permission to use it, you can get sued.
For the sake of those of us who are paranoid/cautious/don't want to get our asses sued, it might be helpful to clarify the rights to all parts of your art. (And realize that if someone who uses your art gets sued, you could get sued too).
