Angel, you really are an angel haha! No but seriously I think you handled this whole situation very well, and to be honest I think the girl who heavily copied your art is going about this well too. It's not common that they apologize and in such a polite manner. To her real quick, you are not an awful human being, we all make mistakes, and you've been brave enough to admit that. I'm glad you guys were able to resolve this. I hope she doesn't receive anymore hate, like you said, not cool.
