thank you for the information.
no, they haven't any of my permission and this is not first time, when people says, that saw something with my art in sell without premission. few times i sent mail to the administration of DA, but they said "we haven't prove that art takes from this site". and thats true because this sylvana are in offical blizzard fan-art gallery and i don't know where can be else
so i don't know which law can stop those seller-guys. pirates are everywere, especially on the internet. but i don't like scandals without law-base.
anyway, probably this is some kind of my art popularity. when people liked movies, music or art - pirates will take it...so, let it be
i'm glad, that people know the author and thanks for information again. have a nice day!
