Any characters I create or depict are Up For Grabs. I don't bother copyrighting anything, and I have no intention of "squatting" on something just to be dickish.
Of course, characters that are already
copyrighted, such as Warner Brothers' Lola Bunny or Walt Disney's Zootopia
or Nellie Kitchen's Furry Experience
webcomic, are fan art. And as fan art, it's good form to acknowledge the rightful creator somehow, either in the description or on the artwork itself. I hope I've done that consistently; if not, let me know, and I'll make it right. Fair's fair, y'know.
However, for any of the bunny / kitty / whatever characters I've created, they're Public Domain. One of the big, beautiful things about Deviant Art is how much inspiration there is on display. So much poignant, meaningful, inspiring pieces, both with copyrighted characters and with "pulled from thin air" ones, that I get ideas. My thinking gets bent into new directions, and I'm delighted at how very creative and ingenious the artists here are. Therefore, the dead-last thing I should be doing is going all Ebenezer Scrooge and kvetching at deviants to not touch my stuff. Touch it all you want, it's there to maybe take your thinking in a new direction, or spark an inspiration. Happy pickings, peoples.
