Yeah... I know the feeling. Me and a bunch of other group admins have removed the stole version and posted links to your DA and the original piece, removed her from our midst, reported her to FB and he is now blacklisted. I do hope that makes you feel better
Very nice style and colouring - and congratulations to whoever designed her (I'd guess it was the comissioner?). She's so cute and slender that for a minute I wondered if she's not some kind of a cat-pegasus hybrid. What does she need those terrible claws for?
