Well..in the beggining i thought that too but, reading her replies, i realised this girl is dumb as a door.
Send her a message telling her that you know all of her pictures where colorized by you and if she didnt take em all off of her site, you will denounce her to deviantart staff.
If she got cared with the replies in Olga s picture, she will get even more scared when he read your message.
she s not just taking your work, modifying it and putting them on display..she s also selling them and that s uber wrong.
